Valid in the US and Canada.
Microsoft will sell you an Xbox One for $399 if you 'ditch' your 'old' PlayStation 3 (also applies to some Xbox 360 models).
That's right, Microsoft is giving $100 store credit towards an Xbox One if you trade-in a PlayStation 3 at one of its retail stores.
Here's what people are getting on their emails:
Apparently, the trade-in deal is only available at Microsoft's retail stores in the US and Canada, and it applies to the PS3, Xbox 360 S, or Xbox 360 E. It will be valid between January 23rd and February 28th.
