Getting money for your used books

You can sell your used books online at Cash4books. It's free and easy. You start by typing in the ISBN from your book and can immediately see what they will offer you. They will pay for you to ship the books to them and then they send you a check or pay you with Paypal within 3 days of processing your books.
What a great way to clear out some clutter for spring!

Here are some other sites that buy used books:

Blue Rectangle
Sellusyourbooks.com
Webuyyourbooks.com
Ckybooks

Most of these sites will donate or recycle books that are not in "sellable" condition.
