Hey everyone. I use swap.com to trade books for free (well you just pay the postage and can earn free postage by referring friends). You just list all of the books that you are willing to trade or swap with other people and the site will tell you which books you can get for free. It's a pretty awesome site and you can also list your DVDs and video games. I would trade my book for video games and have been using the site for years. Thought I'd share so you can check out what you can get for free!
