Used Math Textbooks

Where can I get the best rate for used college textbooks?

I know selling to the store I bought them from at my school will not get me far as much as I could get. They are all well taken care of and pretty much like-new condition. I am hoping for insight from people that are students and have compared between local places and online. Thanks again everyone for the help.

1. At a used book store maybe
2. Half.com is good, and I had a good experience with BookByte.com, with a killer price. Tried Alibris.com and they messed with me a little bit.. I don't know anything about local bookstores, but college bookstores are a ripoff. The last book I bought was $130 at the college bookstore and $12 online, it was the teachers edition but that just means I got the answers too! And it got there in about a week. Just go to bookbyte.
3. i use bigwords.com
