My daughter and I have been using eBay as our “go to” bookstore lately. As an eBay seller, I’ll assure you that the fees are far less when selling used items, including books, on eBay. When selling via the big A marketplace, the fees start at about $4, and go up incrementally. Obviously, selling anything other than textbooks or other high end items on the big A marketplace is not worthwhile. However, eBay’s current fee structure is 12% for books, which means sellers can offer better prices to customers. Also, big A has a flat fee of $3.99 to ship a book, unless the seller offers “free” shipping. As USPS offers “media mail” rates for smaller books, the shipping can be cheaper via eBay. Win-win, right?
Here’s an example of a book that I have placed on the marketplace for a client; basically big A gets $6 of the $17 price:
The fee for that book on eBay would be $2.04. The difference between selling via eBay vs big A is 23%, which is about $4 on a book that costs $17.
Let’s say you’re a bottom feeder looking for a deal. Here’s what happens with a $5.50 book listed via the big A marketplace:
The sale price is $5.50 and the fee for selling it via the marketplace is $4.21, which means the seller gets $1.29. Not many sellers will opt for such a small amount, which is bound to drive up the prices of used mass market paperbacks and/or popular hardcovers. By the way, as of this post, this same book is available for $3.34 on eBay, while the lowest possible price on big A is $4.75. Clearly, bottom feeders need to go to eBay for book purchases. And, while there, check out all the other goods available, from electronics, to clothing, to collectibles— often at better prices than you’ll find anywhere other than the neighborhood yard sale.
One reason buyers flock to big A is the user reviews. Unfortunately, those reviews are not particularly reliable. Big A is purported to fighting this issue, whether banning reviews by customers who have not purchased the item being reviewed, or attempting to control “paid” reviewers. Lately, the issue with reviews on big A is a problem with “hijacked” reviews, where in a product’s reviews are actually for a different product. Certainly, if you must read those reviews, really read them, and don’t be fooled by the number of stars highlighted. All in all, while there may be more variety available on big A, the prices are probably better on eBay.
As a matter of full disclosure, I sell on both big A and eBay. My eBay store is here:
We’ve all heard the old saying that states it is not good when “one hand doesn’t know what the other hand is doing.” Basically, when an organization gets too big or too disconnected from itself, then there is at a minimum a loss of cooperation, and at worst, the organization works against itself.
Honestly, this is just on example of the problems at big A. Lots of articles have been published about problems there. The most troubling ones (for consumers) are the
