Not only did you miss the LARGE XBLA thread already dedicated to this on the first page of the deals forum, but you were beat to the punch by 10 minutes even though you double posted. Mad face palms. Now I feel worse for bumping this. Please at least scroll down the first page before posting new threads.
I actually didn't realize this was only a one-day sale, so thanks for posting it anyway. I have to hound some friends to buy Fez and Spelunky at that price.
