i just got ripped off by my college bookstore. i spent $478 to buy them, and i got $45 back. and that was only the ones they were going to use next semester. for the ones i could sell, i only got back 22% of what i paid for them used. and now im stuck with 4 books that they didn't want, one of which cost me over $100. it an absolute fucking scam.
Yea, I bought a couple book off of www.half.com it's pretty legit. And you can get a much better price than from the school bookstore, which always jips the shit out of you. Try half, but it's always better right before first semester than second semester.
