It was indeed supposed to be $449. However, the store manager told me about the BB ad flyer I showed him on my phone that it was either a typo or a regional ad from somewhere else. But since I brought it to their attention he treated it like a competitor's ad and price matched. Plus, there was already a deal going for free Live for a year with console purchase. Win for me.
The manager sold you the wrong bundle. It's a company-wide sale and it's on the bundle that doesn't include the Kinect. I got the e-mail for the flier myself yesterday. So, due to the manager's lack of being able to tell the bundles apart, you managed to get a pretty great deal there.
