If you need some new items for your 360 such as a headset or a Live subscription, you can pick it up from
Best Buy and then get to watch Watchmen for free. The least expensive thing on the list is a 3 month Live subscription or a 1600 point card for $20. Not a bad deal if you were going to pick up something and see the movie anyways. If you don't want to watch Watchmen, I'm sure you can just go into another screen of your choice. Perhaps the Jonas Bros. movie is more up your alley. I'm heading out this Friday to catch the flick actually.
