That's funny. Where I am in Michigan right now, they're practically sold out after every restock.
I'm stuck basically twiddling my thumbs and looking through products online that I would like to get, but can't.
So, I'm basically in glennchannell's boat here.
The best card that I've pulled from one such cube from a few years back was a Mark Ingram Rookie card rookie NFL patch card. There was also a Reggie Bush rookie in there too. Those little things are goldmines if you get lucky.
Didn't think I'd get this far from building robots in the garage, but here we are now. Wish I could make a robot that could scan every image of my cards in here...
