Turning $600 into $6,000 in 3 Months: A Start-Up Success Story


The Roadmap to Entrepreneurship consists of three steps:  Start Up, Scale Up, and then Step Back.  I’ve been embarking on a blog series this year to explain each step in more detail.  Today’s post will highlight the Start Up phase, thanks to a guest interview with a brand new Amazon seller.

Say hello to Nathan Walsh.  Nathan has a day job – although it’s part time – which allows him to build his Amazon business on the side and re-invest his profits.  He tried to start his Amazon business during the “FBA Freeze” last December.  The warehouses were so backed up that Amazon put a temporary ban on new FBA sellers until the Christmas rush slowed down.  Nathan used this time to prepare by reading blogs, watching YouTube videos, and learning from the FBA community.  As soon as the ban was lifted, he jumped in with both feet.

In his first three months, Nathan sold $15,000 on Amazon, profiting nearly $6,000.  His ASP was $19.45, and he achieved these numbers selling 95% books.  His start-up capital?  Just $600.  You can’t beat those margins!  That’s why many Amazon sellers get their start selling used books.

What stood out most to me was Nathan’s turn rate.  He sold 81% of his inventory in the first three months.  He did this by pricing competitively and by sourcing books with a sales rank under one million (he only had 13 books ranked higher than a million).  This “fast nickel” business model set him up for some early wins, and as his business expands and matures he can afford to start purchasing some longer tail inventory.

If you’re still sitting on the sidelines waiting to jump into the FBA game, take a page out of Nathan’s playbook and jump in with both feet!  If you start your own Amazon adventure, be sure to leave a comment below and let us know how it goes.  I love to hear success stories from other sellers, especially those who start up for the very first time.  And remember, there’s no better category to get started with than books.  But don’t take my word for it – learn from Nathan’s story below:

Nathan, thanks for sharing your story on the blog!  Tell us a bit about yourself.

My name is Nathan Walsh and I currently live in western North Carolina. I am in a career medical profession working part time. Aside from this, I am working diligently every day to create a sustainable business that can provide the financial freedom that I’m sure many of us are looking for.


What’s your favorite breakfast food?  Being I am from the South, I would have to say livermush. You can find it at most every diner in my area, and it is served with that southern hospitality.


Colgate or Crest?  Crest. Never had a cavity. I will let that speak for itself.


Have you sold online before?  What attracted you to selling on Amazon?  Before starting my journey with Amazon FBA, I had sold just a few of my personal items on eBay. Once I heard about the Amazon FBA program, I was all in. Having the opportunity to reach a massive audience without having to drive traffic to my own website was a no brainer for me. Also, having Amazon’s team pick, pack, and ship my products to my customers and handle customer service was very valuable to me. We should all feel very appreciative to have such a great opportunity.      


Do you sell MF, FBA, or a mixture of the two?  What other platforms do you sell on?  I have never sold MF. On Amazon, I have utilized the FBA program for all my sales. Outside of Amazon, I have listed products on eBay and the Facebook marketplace. I personally believe it is a good practice to diversify your online presence.

You tried to start selling on Amazon FBA during the “FBA Freeze” in December, so you weren’t able to send in any shipments prior to December 19.  How did you prepare during that down time?  Were you still sourcing?  What materials did you study along the way – blogs, training videos, mentors, etc?  When I heard about the temporary “freeze” for new sellers I was highly disappointed because I was about to send in my first shipment. Instead of letting this adversity get the best of me, I made the decision to use this time as an opportunity to research and continue to source products. This preparation was key to my success when the ban was lifted. I focused on sourcing books every chance I got, and watched many YouTube videos as well as read many blogs. This time enabled me to learn the “nuts and bolts” of the business. One of the resources I used was a group on Facebook called FBA Rockstars. This group consist of many new sellers as well as experienced ones who worked together to answer common questions for beginners. I would highly recommend this group when just starting out to learn the basics. I also watched a variety of different YouTube channels to get the inside scoop on many different techniques. My favorite blog to read was This blog was very beneficial to my success, and it takes a more sophisticated approach to the book business. (author’s note – I didn’t pay Nathan to say this, I swear!)


What tools/software do you use?
-InventoryLab for my listing software. This allows me to keep all of my inventory organized and speeds up the listing process.
-The Dymo 450 Turbo for printing item labels. This works well in conjunction with Inventory Lab.
– TaxJar for my sales tax needs. It helps you comply with sales tax regulations and answers all sales tax related questions.
– Just started with the eFLIP software. Great software that helps you find profitable books to flip from merchant sellers to FBA. This software takes online book arbitrage to another level.
– I understand why many sellers turn to a bluetooth scanner paired with a downloaded database like FBAScan. However, I just use the Amazon Seller app. It’s free to use and gives me all the information I need to make smart buying decisions. If you have bad reception in many of your sourcing locations or will be traveling far away from home, I would recommend using a downloaded database paired with a bluetooth scanner.
– Keepa and CamelCamelCamel – These are must have tools and are also free to use. These tools give you a more detailed history of the product you are looking at buying. I would highly recommend learning how to effectively read these charts early on.
-Goo Gone, Scotty Peelers, and a shipping scale round out my tool arsenal.


What are your primary sources?  (General categories – don’t give up any local gems!)  The majority of my books come from thrift stores. I go to the same book sale in my area every month. All other methods of sourcing come from online arbitrage.


Any unique sources that you’d like to share?  Facebook marketplace. When I travel to other towns to source, I am always looking the night before for people selling their books. Also I use an app called Offer Up which is similar to the Facebook marketplace. Letgo is another similar app that I have not yet used, but would imagine this would make another great way to look for books.


You’ve spent $2,186 and generated over $15,000 in sales in just three months.  You can’t beat those margins!  How do you see the business scaling over the next 3 months?  I have been very fortunate that the Goodwills in my area have been putting all donated books on the shelves. However, they have now started scanning the books themselves and keeping the ones that fit their parameters to sell online. Most of these are the ones we are all after, but occasionally one slips by or you can snag one that has the barcode covered. So far, Goodwill purchases have been a huge part of my sourcing efforts. Now that this has changed, I will have to take a step back and look at other sourcing methods. I would predict a decrease in sales until I can find other solid sourcing methods. My number one goal is to scale the business, and I am constantly working to find ways to do so. I hope I can continue in an upward trend.      


If you have a current job, do you have aspirations of quitting that job soon? (Don’t worry, your boss won’t read this!)  I do not see myself quitting my current job. I look at this job as a great way to fund my daily living while I can funnel every penny I make from the business back into my business funds.


What’s been the hardest part of running your business so far?  Consistently finding profitable books to sell. Some days are great and others are not. Staying persistent and finding a variety of sourcing methods has been key for me thus far. It can also be hard to remember that I can only do so much at one time, and not all days are winners.


What have you enjoyed the most about selling on Amazon?  Being Amazon is the world’s largest online marketplace, I feel privileged I am able to sell on this platform. I enjoy being able to be my own boss and work the hours that work best for me. It’s nice being able to do some hard work upfront and then sit back and watch the sales start rolling in. The FBA program really gives you the freedom to spend more time scaling your business rather than spending all of your time with busy work.


How many hours are you working in a typical week on the Amazon business?  

As of now, I’m working at least 50 hours a week on my Amazon business. I hope to decrease this number by making tasks more automated. If I want to continue to scale my business, I know I will need to make parts of my business more efficient to free up more of my time to do more “big picture” planning.


How far away do you drive to source inventory?

The farthest trip I’ve taken was an hour and a half drive. On average, I drive anywhere from thirty minutes to an hour away from my hometown.


Have you done any online sourcing?

Yes, I have bought books from Amazon to resell on Amazon. I have also spent many hours sourcing on Ebay. I am also looking on a consistent basis at classified sites to find good deals in my area. I have recently signed up for Eflip, which enables me to find low merchant fulfilled prices on books and then turn around and send the books in FBA at a much higher price. The advanced features from this software help me to narrow down search results, which in return helps me find profitable books to flip much faster.


Your turn rate is exceptional!  Can you tell us a bit more about your pricing philosophy?  Do you use a repricer?  Do you match the lowest Prime price?  How often do you reprice manually, if ever?

Although I’m a newer seller, I currently have 17 reviews and have 100% feedback so far. Each book is unique, so I always try to be as transparent as possible with the book I’m sending in so I can maintain 100% positive feedback. I do clean up some of my books by wiping away any marks, smudges, stickers, sticky residue, etc, but recommend not spending a lot of time doing so. I have a default description for each book condition, but always make sure to make note of any flaws. I make my descriptions as specific as possible and try to put myself in the shoes of the buyer. I try to stay positive about the book’s condition while being honest about the book they will receive. I think my personable condition descriptions and bold, professional company name have helped my sales conversion rate.

I’ve never used a repricer. I price very competitively. Sometimes, there will be one or two sellers coming in at a much lower price than the other sellers on that book. In that case, I will price above them and wait it out to turn a higher profit. I do match the low FBA offer often. Sometimes, I go in right under the lowest FBA price. If I have a spare few minutes during my day, I will grab my phone and reprice. Although I’ve sat down and had mass repricing sessions a couple of times, I mostly do this in little chunks every now and then. On average, I’d say that I’m repricing every week or so.


You stick with books mostly with a rank under 1 million.  This has helped you sell them quickly!  Do you plan to ever branch out and source higher-ranked books?  I hope to start sourcing higher ranked books more often, if the numbers add up. I have found that many books with higher sales rank can make the day from time to time.


What’s your target list price for books?  Minimum list price?  (Your actual list price is $20.36)
Instead of looking so much at the target list price, I’m looking at my return on investment. I have no problem with turning a $0.25 purchase into a $2 profit if it looks like an easy flip. I basically look for any books that have a good return and are likely to sell. There are many different factors I consider for each book, such as the buy price, condition, average price and sales rank, FBA offers, and more.


How much money will you spend on a book?  (Your average is $2.36)

So far, I think the most I’ve spent is around $30 or $40. For me, it’s all about the numbers. I would spend $100 on a book if I felt confident that I could sell it and make a good return on investment. If the book has a strong sales history and price history, I’m more than willing to pay more to make more.


If you could go back in time three months and start over, what would you do differently?

When I first started, there would be some books I would put back down believing the condition wasn’t up to par. Where as now, I pick up books that cosmetically don’t look as good as long as they don’t have water damage or are a complete disaster. Especially textbooks. Most college students just want a book at a good price. Now, I just make sure to make note of any flaws for the buyer. I use to put back many books that I was too afraid to sell because of condition. I still highly recommend buying good quality books and being completely honest about the condition, but there are some books I regret putting back on the shelf.


What advice would you give someone who’s on the fence about starting an Amazon business?

I would definitely say to jump in. With an Amazon business, there’s a lot to gain, but not a lot to lose. Unlike most businesses, it’s relatively cheap to get started, especially if you’re buying books. So the worst that could happen is that you would lose a few hundred bucks. The potential profits are so high, why not start? You can always test the waters and see if it’s a right fit for you. Even if it’s not the right fit, you haven’t lost a lot. You are going to have some failures. I’ve had my fair share. Don’t get discouraged and just know that everyone has many of the same learning curves. Realize not every day will be a winner, and there will be some mistakes here and there. Building any business is not easy, and the same goes for Amazon. Treat this like a business and you will see results. Stay persistent and try to learn something new each day. Look at everyday as an opportunity to make money. Remember every time that you’re watching Netflix or surfing on Facebook, you could be building your business. Also, stay organized. This will help declutter your mind and turn your focus to building and scaling your business. I think Amazon FBA is a great opportunity for all of us, and we should feel privileged to be able to sell our products on such a great platform.


Do you see yourself sticking to this current business model, or do you think you’ll pursue Private Label, Wholesale, Online Arbitrage, etc. in the future?

The book business has been good to me so far. I really like sourcing and selling books. It’s hard to find other products that have the returns that books have. Private labeling is something that I’ve definitely considered, and may consider at some point in the future when I feel like it’s the right time. I would rather learn the book market first and try to succeed in this than try to jump into hundred different things. I would like to continue to make books work and build this business, even though there are some challenges I face. I have also looked into Merch by Amazon to provide additional automated income, but have just scratched the surface so far.


Anything else you’d like to share with other Amazon sellers?  Again, I think Amazon FBA is a great opportunity for all of us with minimal risk associated with it. Mindset is key. Amazon is always changing. When it does, adapt to it. I also believe that research and education is very important, but the only way to see real results is to get out there and take the plunge!


  1. Thank you, Nathan and Caleb. Great motivational story. I am where Nathan was back in November/December. studying and… almost ready to start.

  2. I’m just getting started. Lots to learn. I have bought about 40 books with eflip. The first books were listed about a week ago. Haven’t sold anything yet. How long on average does it take for the first sells to come in? I have more higher priced books with all most all of them under a million rank. Interestingly I had $600 to work with as well, although did get another $200 to spend on my business. I have spent close to $500, so hope I didn’t put to much into each book on the first round. I really need to get some money back so I can keep the money snowball going. Thanks for your inspiration!

    • Seth-I am relatively new to selling books on FBA as well. I sent my first shipment on February 14th and made my first sale on March 5th. Sales keep picking up steadily. I hope that helps.

    • I expect to sell about 10% of my books each month, so on an inventory of 40 books, selling 4-5 would be about right. Newer inventory tends to sell faster than older, stale inventory.

  3. Seth, I have been an FBA book reseller for the past 6 months, with over 20k in sales. Yeah, I know it’s not a large amount of sales, but I do think 20k in sales will qualify my next statement. This Eflip software is not 100% truthful. I’m not going to call it a scam, since there is SOME truth (a very small kernel of it), but I think many people are being misled. People are not going to spend double, triple, or quadruple the merchant fulfilled (MF) price, just to get an item on prime. Your average customer will most likely wait until the prime price drops to a reasonable margin from the MF price, or just buy it MF. The idea that you can buy a book for say, $8 and sell it for $35-$40 on prime is not true. I mean, think about it – would you be that dumb? No.. so why would a person who is looking to buy your college textbook or the instructional book (two most profitable categories for books, FYI) you are selling also be that dumb. I think Caleb is a really smart guy and knows a ton about books, which is why I have followed this blog. But at the same time, he’s smart enough to know that people will trust what he says, especially when they are new to selling books and/or in need of fast money. I hate to see people being misled, which is why I’m speaking up. I’m actually surprised no one else has spoken up. If I’m wrong on this hypothesis, I would encourage someone to please provide proof of completed sales for these MF books at such an extreme margin on prime. I hope your business works out for you.

    • Hey Bryan – sorry for the slow reply in seeing your comment. Prime customers absolutely pay more for Prime books than MF books. Not every book has this “FBA price bump”, but many do. When it comes to textbooks especially, students need the book yesterday and will gladly pay for Prime shipping, at (almost) any price. Business buyers using their company’s credit card will likewise pay more, much more in some cases, to get the book they need quickly, instead of waiting 2 weeks to get it from a MF seller.

      From several surveys, 50% of Amazon’s customers prefer Prime, and roughly 10% of Amazon’s sellers sell FBA. This supply/demand mismatch is why eFLIP works. We have customers who have been using eFLIP for 18 months now and are still loyal customers. If it was a scam they wouldn’t have stuck around. We had customers (more than one) sell over $50k of eFLIP buys in January alone this year.

      This online arbitrage model isn’t for everyone – there’s a learning curve and it requires more capital than buying books from local thrift stores – but for those who have figured it out it’s a solid source of books to flip. I’d be happy to give you an extended trial of eFLIP to test it out for yourself (if you’d be interested). No scams here!

  4. This is great! Thank you for sharing.
    I am just “jumped” into Amazon FBA, and your words and advice are helpful & encouraging.

    Best of luck to you in the months to come.

  5. Caleb,

    Is it possible for those of us just starting out to really compete with the large volume FBA sellers for textbooks flips? They can cut their margins way down and still do OK due to their large volume of sales. Flipping books sounds like it would work, but what about competing with the large sellers?

    Thanks for your answers.

    Dave w

    • Yes you can. Larger sellers experience economies of scale, but they also have lots of blind spots due to their size. Smaller players can be nimble and adapt quickly, just like other in other industries. Even for people who go to thrift stores, there are many bulk players who are listing hundreds if not thousands of books every single day. We can’t keep up with them, but this market is rather large and the opportunities are out there!

  6. Hi,
    I really want to do this. It is Aug 28 and I know Amazon charges extra if your products have been sitting in their lot for some time so i’m wondering when should i start this now or wait until November so my books sell in December? and what are the real steps. Change my account to pro with the $40 a month charge, should I have a business name and company profile based on books? What fees besides the $40 a month fee will I be seeing from Amazon with doing this, and you buy books the place you buy from on eflip sends to Amazon and you just wait until It’s there to post? Are the photos included. No one explains in depth with every actual step.

    • Hey Desirae – looks like you’re referring to buying books with eFLIP or online arbitrage? If so, you would buy books on Amazon, have them shipped to your house (or a prep company – not to Amazon directly), then inspect the books and list them on Amazon via FBA and ship to a fulfillment center. You don’t need to pay the $40 pro merchant fee, but once you get up to selling 40 books a month the fee pays for itself since you save $1 per book sold if you have a pro merchant account. Let me know if you have additional questions!

      The storage fees aren’t enough to sit on the sidelines until December – send ’em in and let them sell! Many textbooks sell quite well year-round.

  7. good job, very important and real info

  8. I will start my fba business in a few weeks (sourcing the products now), and your article is helpful and encouraging, thanks for sharing!

  9. This is my reply to eflip being a scam.
    I tried the free trial and purchased a nursing text book for $5 in September the lowest used price for that book is $54 now. And as far as what Bryan was saying about what people will spend. Why is their arbitrage? People can find the same bargins but because of many factors choose not to and even purchase items online at a higher price than in the actual store. I am a believer in eflip and will be a returning member once I receive my Q4 funds.

  11. Hi folks,
    thanks for the great article and comments. I am a newbie and have sold my old textbooks through seller central. Now I am looking to source online and book fairs/library sales. I am starting with a small budget so trying to be judicious on what tools I should spend it on. Can anyone give suggestions? Eflip or not? I tried the Bookscanner app but is there something better out there to scan quickly on the go?

  12. I fail to see how the buy on amazon and resell on amazon can really work. Yes you can find lots of used books for $5-10, but there are lots of sellers offering them with prime shipping for $15 or so. That means minimal profits so to make $100 profit you’d have to buy 40-50 books. When I paste some of the data from active sellers into the Fulfillment by Amazon Revenue Calculator, it often comes up at a loss. Why are people selling these at a loss? To keep out competition?

    Something else that is strange is some sellers have very high prices. How do they ever sell?

    • Some sellers are selling at a loss because of poor repricing strategies, or because the alternative is to pay $0.15 to destroy the inventory. So selling at a loss of $0.14 is still a better decision. For the MF to FBA flips, it’s a numbers game. You have to sort through the unprofitable books to find the small percentage that can be flipped for a profit. Check out the new eFLIP Outliers, as you can search for Prime prices within main search, making this process much faster.

  13. Hi Celeb,

    I would like to try eflip but, my worries are: I am totally new to this all FBA thing and selling books , when i say new I mean i have never ever sold anything in amazon so i dont know even those terms you guys are using besides, lisiting and asking for reviews also its I dont know. my question is: is there any dummy course? which covers all of the process of buying and selling books in amazon?

    • Apologies for the slow reply – if you’re brand new, I’d recommend learning by flipping books from thrift stores rather than jumping into Online Arbitrage. You can make your mistakes on cheaper books this way, then once you get your sea legs under you, you can move up to OA. There are a dozen or so videos in eFLIP University if you take the free eFLIP trial, and lots of free content on The Book Flipper Community YouTube channel and here on the blog.

  14. Its almost 2019 – is this still a strong and profitable business model Caleb?

    • It’s still growing for me and many in our Facebook group. Some sellers have moved away from Amazon with the fee increases, but for those who are willing to adapt, books are still in demand on Amazon so the sales are still there.
