Did you see the Apple/Pepsi commercial during the superbowl?

If not, check it out here.

So Apple & Pepsi are giving away 100 million iTunes Music Store songs. You have to buy 20 oz. or 1 Liter bottles of Pepsi, Diet Pepsi or Sierra Mist. 1 in 3 wins. An excellent deal for those that drink a lot of soda anyway. My problem is that I can't seem to find a store with a good supply of them in stock.
