Amazon aims to save you money at college.
The online retailer is renting textbooks. It just launched "Amazon Textbook Rental," allowing students to rent textbooks at savings up to 70%, according to "The Motley Fool."
Students and parents can search the site for books, then click "rent" on the ones available for rental.
Rentals can also qualify for free shipping, and come with a prepaid label for returns.
