buying textbooks

I'll soon be a poor college student and was wondering how to get cheap textbooks. As soon as I know what books I need I'll check out half.com, but I was hoping for other tips. I also seem to recall someone mentioning (maybe not here) a textbook exchange website where you get points by sending out your old books and can then use them to get free books. Does anyone know of something like this?
