Wondering how to get rid of old books, movies and music. Don’t throw them away. You can swap them for books, DVDs and CDs that you are interested in.
Wall Street Journal reviewed three sites Paperbackswap.com, Swaptree.com and Bookmooch.com and you can find out the details.
The way it works is you post all the books you're willing to swap with other site members. You get two free credits for posting your first 10 book titles. (One credit is redeemable for one book.) You earn an additional credit for each of your books requested by (and sent) to another member
When someone requests one of your books, the swap sites create an automatic mailing label (preprinted with the recipient's address) for you to print out wrap around the book and mail it. Price for shipping per book is around $2.00.
Paperbackswap.com, which is the oldest site also allows you to buy credits for $3.45 a credit. Bookmooch.com has a similar model but with less choices and not so well refined service. In addition to books Swaptree.com users are allowed to trade one-to-one swap of DVDs, CDs and movies too.
