Stopped by one of my local radio shacks today. They had a Kinect bundle w/ gunstringer, kinect adventures, and fruit ninja for $70 off (normally $110 I guess). Clearance price was $39.99. Then at the register I found out that all clearance stuff was an additional 25% off. That brought it down to $29.98. I was able to get a military discount of 10% off on top of this (didn't include in title as most won't get this). I ended up paying $28.60 which included tax for the bundle.
I was skeptical about kinects at first as I sit on my ass for most games I play lol. This seemed like too good a deal to pass when I still see them for $100 at walmart. Embedded is the receipt. This might vary by store, worth looking though.
Edit: They told me the additional 25% off was only for a few more day, just fyi.
