I mailed my books in to sell without reading any reviews and just purely based on the criteria BookByte has on books it will accept and pay for. Went for it because BookByte offered the best prices by far compared to other buyers online. I did get a little worried when processing went a bit slower than I expected and reading reviews on other people losing their money and books. My fears were unfounded, my selling order was processed and I got the quoted money with no trouble. Send your books if you are sure you’ve maintained them in good condition and it meets the criteria listed on BookByte. And read over their policy about how they won’t return books they won’t accept; maybe have pictures of your books beforehand to present your case just to be on the safe side.
