Operation Smile is kept running by donations and volunteers from all over the world. They receive donations from individuals, as well as companies. One of those companies is Campus Book Rentals.
Campus Book Rentals is a great alternative for college students. Rather than buying ridiculously expensive text books, and hope to sell them back for a little bit of money, Campus Book Rentals offers you the chance to rent your books for a great price. They have a huge selection of books and there is free shipping as well. I'm looking over the site, at all the books I used and wishing that they had this available when I was in college.
As I mentioned, Campus Book Rentals donates a portion of every book rental to Operation Smile. Their goal is to cover the cost of at least 1,000 life changing surgeries. Yet another reason to use Campus Book Rentals for your classes this year!
