This site is now on Facebook. Site allows you to advertise your books to students on your own campus — no going through the bookstore. So, the savings are significant because you’re able to cut out the middle man. In addition, you don’t have to spend time and money to send your book to someone, as you would if you used Amazon.com’s marketplace. You can meet up with your buyer or seller in the library or on the quad, or wherever, to make the transaction. Site gets bonus points for being well designed and easy to use. Obviously, though, this site will only be successful if many students on your campus are using it, otherwise, you’ll never find the books you need.
