If you're a Diet Pepsi drinker, then be sure to pay attention to which package you buy in the store, because from now until the end of May, they are offeringjust for drinking Pepsi. You need to collect 8 Movie Bucks and you can find them in:
2 liter = 1 Diet Pepsi Movie Buck
12 pack = 2 Diet Pepsi Movie Bucks
24 pack = 3 Diet Pepsi Movie Bucks
So for buying something you'd normally buy already, you can go to the movies for free!
