Someone doesn't know how to add.
Wii games = 50 coins
Wii games = $50+
Cards = 800 coins
That's 16 Wii games worth of points, at $50+ a pop, your FREE gift (a pack of $15 cards) cost you $800+. And that's not even figuring in each $50+ game has a lot more + in it, not including tax.
EDIT: And for the record, I think the hanafuda cards a great prize, just not for what they want for it. I'll wait until I can get a set on eBay and save my coins for the OSTs.
