The Xbox Digital store currently has the Call of Duty Ghosts digital Hardened Edition for $40. This includes the base game, the Season Pass, as well as a plethora of exclusive digital items including special gun skins, player cards, and a character head.
I didn't see this mentioned anywhere after searching but thought it was noteworthy. $40 Makes it even cheaper than what the regular edition of the game is currently going for the Xbox 360 marketplace.
Can be purchased online or on your Xbox One.
(Edit) If anyone can verify the same price is showing on their Xbox One I would appreciate it. I own the game so it doesn't show for me.
