It's officially Halo 4 release week and a few retailers are doing all they can to make sure you pick it up from them. Best Buy is offering $20 off the price of an 12 Month Xbox Live subscription when you buy a copy of the game with it, and to sweeten the deal even further they're throwing in 800 Microsoft Points so you can buy the inevitable map packs that'll be coming out later on.
