Asda is selling more day one stock of PS4 and Xbox One.
And the supermarket giant says since the products went up yesterday, they've been inundated with orders. It's the fastest selling products on the site in its history. Both consoles are guaranteed for delivery on launch day (November 22nd for Xbox One, November 29th for PS4)

The stock the company has available is the PS4 Killzone bundle and the Xbox One day one edition, which comes with a free copy of either FIFA 14 or Forza 5.
