I'm sitting on 955 of these things. I've got more coming when I redeem my niece's 3DS at Christmas, plus some from Paper Mario.
The free 3DS games always suck, and I actually bought the first couple they offered only to never play them. The Wii is in the kid's room so those games are out of the question.
I bought one of those 18 slot game card cases, and I actually like that a lot. I'd buy another if they were still available. I can only assume they took them away because they actually had to ship a ton of them to people.
Right now I can buy playing cards, shoelaces, terrycloth towels, and other useless crap. The only posters they even have available right now are Donkey Kong.
Anyone else have a ton of coins and no idea what to use them on, if anything, ever?
