Used Math Textbooks

What is the best website to use to sell used textbooks?

We are trying to get rid of some stuff that we do not need. We have a lot of textbooks. I have found numerous websites, but I would like to know which one is best. We would like to sell the ones that we can.

1. depends on how much work you are willing to do. half.com has worked well for me but it takes more time because you end up selling them one at a time
2. half.com is really easy!
3. I would say Half.com but try to deal locally on Craigslist and ask around for students in your school.
4. I would use half.com. or you can try a campus book store but they usually don't give a lot of money.
