SWAP A BOOK: In an effort to cut our expenses on buying books and audio CDs, I have become a member of www.paperbackswap.com. This Web site is fabulous. It contains thousands of books that you can swap with other members for free. Membership is free as long as you submit nine of your own books initially. The only cost to members is postage for sending your books to other members. This service lets us share our books with others and save money, too.
