Save money on books.  Check out Paperback Swap.

What is PaperBackSwap? PaperBackSwap is a free online book exchange service. You sign up there and list nine books that you’re willing to send out in the mail to anyone (just list nine books you have that you probably won’t read again and you’d probably end up taking to a used book store or something eventually). Once you’ve listed nine books, the site gives you three credits. - The Simple Dollar

During these economic times, I think all of us are interested in saving some cash. The Simple Dollar is one of my most recent additions to my rss feed. I like what I’ve seen so far, including this review of the Readers Digest Penny Pincher’s Almanac.
