Renting your textbook is the new way to save cash on campus. "Everyone's looking for a way to reduce the expense, to minimize the cost, and rentals were one of the logical steps," says Jim Henley of the Temple University Book Store. If your college bookstore doesn’t rent yet, just head online. At ecampus.com, bookrenter.com and chegg.com, you can rent books for 50-60% off, and have them delivered right to your dorm. When you send them back at the end of the semester, shipping is free.
