All Microsoft Stores in the United States and Canada will have extra Xbox One units available for purchase beginning at midnight on November 22, a Microsoft representative told GameSpot today.

Supply is said to be "limited," and consoles will be available on a first-come, first-served basis. Head to the Microsoft Store website to find the location closest to you.

Like the PlayStation 4 before it, Xbox One units for those who did not preorder are proving difficult to come by. Day-one systems remain sold out through GameStop, Amazon, Best Buy, and Microsoft Stores.

The Xbox One launches in 13 territories on Friday, November 22 for $500. For more on the next-generation console, check out GameSpot's review roundup.

GameSpot's video coverage of the Xbox One continues tomorrow, November 19, at 9 p.m. PDT with a video demonstration of the hardware and user interface.
