Bookmooch.com is a community for exchanging books. It is free to join, and you are given points for posting books onto the site. When someone "mooches" a book from you, you receive one point (if it is an international mooch, you receive three points). The same process when you "mooch" a book; one point for a local "in country" mooch, except for requesting a book internationally, you only pay two points. The only thing that you pay for is book shipping, which, even sending overseas, is never for that $5-$6, for me anyway, and never more than $3 sending inside the US. It is a great site for bookworms like myself, I would be broke if I purchased full price the books that I mooched from others.
