Shop CD Baby - the best in independent music. I love everything I've purchased from them. They are having a big ol' honkin' sale.
Put 3 or more of the CDs on the sale page and they will be discounted to $5 a piece. Shipping is reasonable, too. Get there and get some.
Full disclosure: I don't get a kickback. I say it because I love them. And I'm a girl - genetically wired to shop and find sales.
