Not sure if this is nationwide or not, but Mattias Werner spotted it in Teeside Park, let me know if you spot it in any other stores.

I'm pretty shocked to see such a massive discount on this so soon, especially since a lot of retailers have been struggling to keep it in stock at full price. It is alsready at low stock, so don't delay, it will sell out pretty soon I bet.

UPDATE:
It's out of stock now, but it appears they are still letting you order at this price, and will deliver it "within a week".
