The bundle I think comes with a game and an extra wireless controller, this is the premium package and then some.
The premium package you can get at Best Buy only comes with one wireless controller, the costco version comes with two. Doesn't matter for me since there's only me myself and I who plays.
You can turn the 360 off and on with the wireless controller, so you sit back on the sofa and turn on the tv via the remote and turn on the 360 with the controller already in your hands.
