Well, this is a weird deal - but a great one! Newegg has a credit offer for the digital version of Assassin's Creed IV on the Xbox One. Buying that for $40 gets you a $60 credit on your Xbox account. This means that you're getting $20 free that you can put towards anything. You could buy Sixty Second Shooter, or buy multiple codes since there's a 5-per-purchase limit and wind up with Halo: Master Chief Collection and something else after selling off the extra codes. This is a crazy deal and something you'll want to make use of if you've got some Xbox-related purchases planned.
