Everyone that has been through college will completely agree with me when I talk about how expensive college text books are... especially when you buy them at the school bookstore.
And I'm pretty sure our teachers are told/paid to say "you can pick up all these books at our bookstore after class" to indoctrinate us further.
While half the students smile and shake their heads in agreement, because they don't care how much the books cost. The others, like me who are the complete opposite, find the cheapest option out there.
RentBack.com is an extension of CampusBookRentals.com, but with RentBack.com you have the option to sell your books to other students giving you the ability to make 2-4x the money you would just renting.
Both programs are great ways to get your text books for a much cheaper price.
Anyways, I love renting books, it's so much cheaper and less of a hassle after class is over-meaning you don't have a huge pile of books stacked somewhere in your apartment taking up an enormous amount of space.
