A Site to Try

http://www.swaptree.com is a great website where you can list books, cds, dvds or video games you no longer want and just trade them for a different book, cd, dvd or video game. It looks super easy to use. Juste enter the ISBN or UPC code, pick what you want in return, print postage directly from your browser, and mail the item. You can even choose someone down the street, if you want, so you don't have to pay postage. There's no entering weight or calculating shipping. The site does it all for you.
