Once a week I pay 3 dollars to play in a tournament my league holds. 3-0 gets 4 packs and 2-1 gets a pack, and I've never done worse than 2-1 so it's at least a discounted pack, at most a hugely discounted 4 packs. I don't buy packs aside from that, but I will be getting a few of those tins with Mewtwo/Darkrai EX when they come out.
