Abebooks, Valorebooks, Ecampus, and Amazon are all about the same in terms of price and reliability, but search all 4 directly to find best bargain. Earlier you search for books better chance you have of finding cheap used versions.
Best deals are on used books, but sometimes Amazon main page actually has better deal, they also have cheap electronic copies. Great buy back program come end of semester...
