Now is the time.
It's definitely the holidays, and that means some aggressive positioning of game consoles. For the Xbox One, not only are there some great bundles, including the Halo 5 1TB Special Edition and the 36 game Holiday Bundle, but for this week, through the end of November 21st, an extra game can be hand. By extra game, we are talking about any number of recent releases, including 'Rise of the Tomb Raider,' 'Star Wars: Battlefront,' 'Call of Duty: Black Ops III' etc.
For example, the Xbox 1TB Fallout 4 Console Bundle can be had for $399 with 'Star Wars: Battlefront' thrown in for free.
The entire selection and offer can be found here.
