It's in the ad, and there's tags on the shelf at the local kmarts for this. One of my local walmarts is beating this deal, at 37.87 for the redsteel 2 bundle, as well.
Picked mine up today. It was in the Sunday ad, but the "Sunday Deals" thread seems to have overlooked it. Maybe no one realized it was the MotionPlus Bundle version, which made it a better deal than if it was just the bare game...
