I saw this site mentioned on Half Off Depot's Facebook page and thought it was a really great idea!
It is a book swapping site (there are also DVD and CD swapping sites - click on the top of the page)
It's pretty straight forward:
List books you'd like to swap with other club members.
•Once a book is requested, mail it to the club member.
•In return, you may choose from 4,778,300 available books!
- Books you request are mailed to you for free.
- No late fees. No hidden charges.
The same goes with the DVDs and CDs.
Go HERE to take a look, the only cost to you is when you have to send a book, CD or DVD that you have listed.
