Reading is passion of mine and though I visit the library often, there are some books that I want to own so I can read and re-read it at my leisure. Books are expensive though but I found this site (paperbackswap.com) that allows people to swap and post unwanted books for free. The only cost is the media mail postage (Most likely $3), but that only applies to mailing out own of your books to a requester. The good thing about getting a book requested off of your shelf is that you get a point, which you can use to get a book that you want. Does anyone else use this site?
