Books

[akutaq]

I'm on the search for websites that I can buy used books from, with the cheapest shipping. The two sites I've been to thus far (and I will continue my search) are:

http://www.thriftbooks.com
http://www.amazon.com (I only buy used books from amazon)

Are there any other sites out there? Right now I'm compairing shipping prices so I can save a buck.
