I've been able to buy books from Half, and then sell them to the bookstore during buyback for a profit. Other times, I've gotten a book for cheaper at another local bookstore.

Be careful not just about the international editions, but numerical editions. I just finished a forensic criminology class where the syllabus specified 7th, but the campus bookstore got the 8th. The teacher ended up making the test from both and throwing a major curve because they were very different editions. However, if you get an older edition than specified, you probably won't get a curve.


Really, just pay attention and shop around.
