#1. Beat the crowds. Your on-campus bookstore is your simplest and fastest route for finding the books you need, but it also can be the most expensive. That said, you may be able to save a little bit of money by arriving at the store as early as possible – the minute you get your list of required books – so you can snatch up used copies.
#2. Use ISBN numbers to comparison shop. While at the on-campus bookstore, write down ISBN numbers and prices for both new and used books, and then use that information to shop around online. Check prices on the Web sites of Amazon.com, Barnes & Noble, eBay, Varsity Books, efollet.com and iChapters.com. A comparison shopping site such as BestBookBuys.com also can be helpful.
