I was in the Swansea HMV store yesterday and noticed that they have the following Xbox Console and Halo 4 bundle.
Xbox 360 Console 250GB
12 months Xbox Live Gold membership.
The sign was a printed sign up on the wall amongst all their console prices so I assume that it is a national deal.
No idea when the deal ends.
Just to add that a friend can't find the deal on-line so presumably it is just instore or perhaps they have not updated their website yet.
They have vouchers instore to get £5 off a £50 spend so makes this £184.99.
