Campus Book Rental is a company with lots of perks:
-save 40-90% off of bookstore prices
-free shipping both ways
-can highlight in the textbooks
-flexible renting periods
-They donate to Operation Smile with each textbook rented
They have a new program that is called RentBack it allows students to rent the textbooks they own - to other students... which is awesome because it makes them 2-4x more money compared to what they'd make through buyback options! (selling their books back at the end of the semester) Isn't that awesome?! you can check out the video below for more information on how it works.
And remember that for every book that is rented through their site they give a donation to Operation Smile. Operation Smile is an international children's medical charity that heals children's smiles, forever changing their lives.
