If you go to the main PayPal page, on the right hand side of the screen is an ad for a $15 rebate on a $30 purchase made using PayPal.

It states that if you make a $30 purchase at any retailer that allows payments using PayPal, that PayPal will give you a $15 rebate. Since iTMS accepts PayPal payments, theoretically you should be able to purchase $30 worth of iTMS tunes and get $15 back. If this doesn't work, though, don't blame me. ;)
