I noticed in my e-mail that Micro Center is selling the Xbox 360 version of COD:MW3 for $19.99. It is in-store only (you can't set up an in-store pickup), but I was able to price match at Best Buy this morning.
Today's Deal of the Day is Sesame Street: Once Upon a Monster for the Xbox 360 Kinect.
$24.99 with free shipping.
