I would strongly advise against selling…

I would strongly advise against selling your books to World of Books. In many cases, they may first send you an initial offer, only to later email you back saying the book has been rejected after review, meaning you won’t receive any payment at all. Instead of buying the book, they often claim it will be “recycled,” which can feel misleading after you’ve already gone through the process of sending it in.

Because of this, you may end up wasting time, effort, and shipping costs without getting any return. It’s worth being cautious and considering other platforms where acceptance criteria and payouts are more transparent upfront.

Great Experience

Easy way to clear out the book collection and make a little money. I've used this company several times to turn in books for resale and will continue to do so. Communication was great so I knew where the books were at in the process and when done with inspection money was deposited promptly in my account. Thumbs up World of Books!
