Helping You with Your Amazon FBA Business

eFLIP and What I Sold: 6/23/16

I’ve been buying lots of books over the past 6 weeks with the help of Caleb Roth’s service called eFLIP and my last item shipped just happens to be a book that I found using eFLIP.

What is eFLIP?

eFLIP provides a simple way to find books on Amazon that are selling at low Merchant Fulfilled prices and high FBA prices.  You begin by entering your filters based on price, ranking, number of offers and year published and the program will go through and give you a list of books that matches your search criteria:

eFLIP Filters

Then you go through the list of books and analyze them to find profitable books.  I like to use the Keepa Chrome extension to check sales rank history:


I also like to use eFLIP’s price calculator to check the profitability based on the buy cost:


If the book meets my criteria, then I’ll purchase it from a MF seller and then resell it at a higher FBA price.

Quick Online Arbitrage

What I like about eFLIP is that it’s very easy to use and I can find profitable books rather quickly.

To take the “quickness of it” a step further, you are paying a flat $3.99 for each book purchased from a MF seller.  This flat shipping truly speeds up the OA process because then when you find a book, you can just purchase it.  You don’t need to spend more time looking for additional books to qualify for free shipping.

Also, you’re not having to spend time playing the “game” of getting lower prices with cash back sites and discounted gift cards.  You just find your books and whenever you feel like stopping, you make your purchase and then move on to something else.

One Negative of the Book Sellers

One negative that I noticed is that many MF Sellers overstate the book condition.  The majority of the books that I receive are usually one condition lower than what’s listed.  For example, if I’m buying a Used-Very Good book, I typically receive a Used-Good book.

Therefore, one of my strategies during my book analyzing is to make sure that I can still make a minimum of 100% ROI on a book that is listed in a lower condition.  For example, if I’m purchasing a Used-Very Good book, then I’ll make sure that the book is still profitable if I list it as Used-Good.

Fortunately, not all Sellers are like that and I found a few Sellers that are very accurate in their book descriptions or understate them.

If you sign up for eFLIP, I recommend using the book-tracking spreadsheet that Caleb provides and add in a column to record the book conditions (listed & received) next to the Seller’s name.  Over time, you’ll accumulate a list of preferred Sellers to purchase from.

Results of my eFLIP Purchases

Though I sold a few books, I don’t have a lot of data to give you at this time.  Most of my books haven’t been in the Amazon warehouses very long and then today I learned that a shipment of 19 books has been damaged. 🙁

I am rather new at selling books so I’m still working on coming up with tighter search criteria and how to price my books for maximum profit.  For now, I’ll tell you about the last book that was shipped.

Last Item Shipped

One of my eFLIP book purchases was my last item shipped.  Below is a screenshot of it in my Payment->Transactions page as proof:

Have a great day,


p.s.  Back to School season is coming up soon and I heard that textbooks are great profit makers in August and September.  This is a great time to sign up for eFLIP so can start getting textbooks into your inventory before then.  Click here to sign up for your 3-day trial to test out the service.

p.p.s.  Caleb Roth also created the Tracking Spreadsheet.  He sent me a note saying that the cost of it is going up on July 1.  If you’re interested in purchasing it, make sure you do so before the end of the month!

    A little late to reading this, but great post. I really haven’t delved into books at at all and worry about jumping into a new category and spreading myself too thin – but I may have to just give this one a try! Question: Is the reason that its easy to flip them because there is only 1 MF offer, so by sending it FBA, you kind of obligate the customer to buy the FBA? I know in some cases, some customers will buy FBA anyways because they are hard wired that way 🙂

      Hi Valerie, there will usually be more than one MF Seller on the listings. But people will buy from an FBA Seller because as you say, they are “hard-wired” to do so. People trust having their purchases sent by Amazon instead of from a random person. Plus, people will pay extra to get their books fast with their prime benefits.

      I find that sourcing with eFLIP is really quick and easy to do. I also worry about spreading myself to thin. However, once you get the hang of grading the conditions of the books, processing them goes pretty quickly.

    @Valerie and I must be on the same train…I’m late reading this post, too! To answer your question, I love reading your “what I sold” posts. You give excellent detail about your process and the tools you’re testing. And, I love that you are transparent and make sure we understand the potential downsides and how you mitigate those risks. Invaluable.

    You’re a class act, Diane. Thanks for all the great info!

      Thanks Ree! By the way, you’re a class act too and I learn so much from your privatelabelpreneur site!

    Hi Diana! Do you have to have two different Amazon accounts? One for buying, and one for flipping? Or do you just use your one account? Thanks!

    • Diana July 10, 2016, 1:52 am

      Hi Amanda,
      I have two separate buyers account. My main one is a Prime account that I use for personal purchases and supply purchases.

      The 2nd one is for flipping. I do not have Prime on it and I have my Reseller’s permit uploaded to it so that I don’t have to pay sales tax.

    Great post! Do you have any update on the results of your experiment?


    • Diana January 7, 2017, 6:54 pm

      Hi Thomas, No I haven’t updated because I want to wait until after the January textbook season first. But to be honest, I came to the conclusion that I’m not a book reseller. It’s a great category and I highly recommend books since they aren’t restricted and the buy costs are lower. But I’m much better at selling shoes. Shoes and wholesale are my main focuses right now and to do that I have to cut out books for the time being. If you’re interested in doing OA books, I do recommend eFLIP and testing them out with their free trial.
