1. Brand new textbooks

A $60 dog-eared copy of the required Economics 101 text is just as good as a new $120 book. Campus bookstores try to tap into the large demand with used book sales and rental programs, and professors are embracing cheaper e-editions. But many students choose to buy their discounted tomes online. Kiplinger.com recommends CampusBookRentals.com, Chegg.com, and BigWords.com. Be sure to search for books by their ISBN number, not their titles, to ensure getting the correct editions.
