Are Books Worth Reselling? An Honest Look at the Numbers
Short answer
On average, no. Books show 38% sell-through in our data (the lowest of any major category and nearly seven points below the 45% average) with the lowest sold-listing counts too. Books work as a volume play with barcode scanning, Amazon FBA economics and niche knowledge (textbooks, technical, signed, out-of-print), not as general thrift inventory.
We build a tool for pricing thrift finds, so it would be convenient to tell you every category is worth scanning. The data does not say that about books.
What the data shows
Across more than half a million eBay sold-comp sets, books return 38% average sell-through, last among categories with a meaningful sample, and around seven points below the 45% overall average. They also carry the lowest average sold-listing count of any major category, meaning thinner demand as well as slower clearance.
Books are simultaneously our smallest meaningful category by scan volume. That is not an accident of our user base so much as a description of what thrift stores contain: 96% of categorized scans are non-media goods.
When books do work
- At volume, with a barcode scanner. The economics of book reselling are a numbers game: scan hundreds, buy a handful. That requires sub-second barcode lookups, not visual identification.
- With Amazon FBA rather than eBay. Most serious book resellers sell into FBA, where sales rank and landed price drive the buy decision.
- In a niche you actually know. Textbooks, technical and professional titles, signed first editions, out-of-print nonfiction. General fiction paperbacks are close to worthless in resale terms.
What to do instead
The useful version of this finding is not “books are bad”. It is that on a Saturday with two hours and a car trunk, the book aisle is the worst-paying hour in the building. Three aisles over, the glassware shelf, the clothing rack and the knick-knack table all run in the mid forties on sell-through, and almost nothing on them has a barcode. Which is exactly why most people walk past them.
That gap is what ThriftAI was built for. Point the camera at an unmarked casserole dish, a jacket with a label you do not recognize, or a figurine with a stamp on the base, and you get the sold price, how often it sells, the spread, and your margin against the sticker in front of you. No barcode needed, which is the whole point.
If books really are the bulk of your sourcing, run them at volume with a dedicated barcode scanner into Amazon FBA. That is a different business with different tools, and it is not the one we are in. For everything else in the store, scan it.
