Microsoft is offering $75 in online credit to encourage certain US Xbox 360 owners to upgrade to Xbox One.
The deal was spotted by NeoGAF user BeforeU, who posted images of a promotion appearing on the Xbox 360 dashboard. It offers a $75 promotional code with the purchase of an Xbox One system or bundle from a Microsoft Store or "local retailer".
According to the fine print, the offer is only applicable to Xbox Live account holders who receive the notification on their Xbox 360 console, and only in the US. The promotion lasts through the end of July.
This credit can be used to purchase games, add-on content, or any other items available via the Xbox marketplace, meaning customers who make use of the deal can download their first full-priced game for free with some credit to spare.
We've asked Microsoft whether it plans to offer a similar promotion outside the US and will update this story with any response.
Microsoft says that Xbox One's July update, which adds Snap functionality to the achievements app, will arrive "in the coming days".
