If you want the green Xbox S and the early enlister deluxe edition of BF1 then the 1TB is advertised as £249.99 in store in the Swansea Game right now.
It is one of their printed adverts as you walk through the door and so it should be national.
OK, went back, got a photo and will upload when I get home in about an hour. Battery about to die on phone.
Definitely £249.99 for 1TB and BF1 Early Enlister Deluxe edition.
