“There are many sites that buy textbooks and used books, but the prices these sites offer vary widely. In some cases, one site may buy a book for one or two dollars, while another site might offer $20. Obviously, it’s worth looking around to make sure you’re getting the most money for your used books.”
“The ISBN (International Standard Book Number) is a 10-or 13-digit number usually displayed above or below a barcode, typically on the back cover of a book.”
“Preferred merchants are those whom we believe to be reliable and reputable. We’ve shipped books to them and have had a good experience. Plus, we usually have a contact at the company who may be able to help with any problems.”
“First, double-check that there is no ISBN on the front or back cover or on the first or last few pages of the book. Older books may have just the ISBN listed without a barcode.”
