The Microsoft Store is currently offering a free $50 gift card with the purchase of any Xbox One or Xbox One S console. The promotional offer is scheduled to end on Sept. 6.
The free gift card is on top of any games that are bundled with the console. There's also the current Microsoft Store promotion that adds yet another free game from a list of four Ubisoft titles (The Crew, Watch Dogs, Just Dance 2016 or Just Dance Disney Party). The free gift card is not offered for any pre-orders for the upcoming FIFA 17 or Gears of War 4 Xbox One S bundles. It's also not available with the purchase of a refurbished Xbox One.
