ahh, this is depressing. i thought i got a bargain by buying my books online, but i went to this site, alltextbooks.com. it compares all the prices for book from various websites. it ends up that i spent more than i wanted to. dammit! i mean it may only be a couple of cents difference, but hey to a poor college student that adds up. damn! what i've learned: amazon.com is more expensive than half.com. just stick to half.com. it's quicker and cheaper. amazon gets you on their shipping and handling. my books were still cheaper online though. so that's a positive aspect of the situation.
