used college textbooks online

I try to find cheap college textbooks. Where is a good place online to do? Apart from Ebay. Thank you.

I am the university and last year I bought all my books in the school library. Used are expensive and used are only slightly cheaper. Many people told me all sorts of places different online that can buy or bid on textbooks at low prices. I do not remember exactly what these sites are. I will try and eBay, but any other tips, tricks or websites would be great. Thank you.

There are many people who sell a lot of things on craigslist http://sfbay.craigslist.org/about/cities.html find your city, then click on "Books" under "For Sale" I hope this helps.
