Colin Stephens, founder and director of Sunrise Books in England, was thumbing through a charity shop’s bookshelf when the manager told him how much she’d come to hate used books. Every few days, she complained, she would have to load the trunk of her car with the shop’s excess donations and shuttle them to the landfill, in her own spare time and at her own expense.
Make sure you know your book conditions up-down-left-right. People who buy a lot of used books, myself included, are very sensitive about conditions. If I buy a book that’s Very Good condition and see that it has writing in it, I’m going to contact you. And 9 times out of 10, you’re probably going to just refund the full amount to avoid getting bad seller feedback (plus it’s often more costly to accept a return than to refund it).
I like to start with BookScouter.com. BookScouter says they’re just for textbook buyback, but I’ve had some good luck checking prices of regular trade books. Book Scouter will tell you what websites will currently pay for each book you’re trying to sell. This will give you a good idea of whether or not it’s even worth selling your books. Remember, all of these websites pay based on what they think they can sell book for, so books with higher demand will sell for more.
