Have you all checked out PaperBackSwap.com yet? This is my new favorite website! :)
I absolutely love to read and have lots of books just laying around. Well, PBS gives you a site where you can trade books with others and earn free books. AND if you sign up right now and post 10 books you get 2 free credits. That means you get 2 free books. I signed up maybe 2 weeks ago and have already received 1 book and am expecting another anyday now!
Check them out HERE. You will not regret it!
