Hi, Right now is prime time for book buybacks. I just sent in 4 college text books and will be getting a check for over $100 fromPlease Log In to view this link!. There are lots of other sites out there. As to which site will give you the best price, it just depends on the books you have. From the reviews I've seen, Amazon.com has 'not so great' service. You can just enter in the ISBN number from any of your books into a search engine and you should be able to find several sites that buy books back. Hope this idea puts money in your pocket!
