Don’t miss this rockin’ good deal! Amazon is celebrating five years of mp3s, and they want you in on the anniversary action. Click here and share a favorite song; then shop on Amazon for any mp3 priced $1.29 or less and buy it for just a nickel! Quick note: the credit did not show up when I completed my song purchase. But when I looked under “My Account” and checked the order, I really did pay just $0.05 for the song! There is a limit of one promotional credit per customer, and all credits can be redeemed through 10/10. Rock on, peeps!
