A few weeks ago, Microsoft announced that it would offer the Xbox One with Kinect bundle, with three free games, for $499 during the holiday season. Now the company has decided to cut the price of that bundle $100 to just $399 as a limited-time promotion.
The bundle still contains everything that Microsoft previously announced. It will have the 500GB version of the console, the Kinect motion sensor and codes to download three free games (Central Spotlight, Kinect Sports Rivals and Zoo Tycoon).
In addition, the stand-alone Kinect sensor for the Xbox One also has a temporary discount down to $99, a savings of $50 from its normal $149 price tag. Microsoft has not announced when these promotional prices will end
