SKY - Pay Once Watch Forever Packs were reduced to £30 each from £70 in my local Asda Store. This includes sky dish, sky box and remote and 4 months worth of free Sky TV. I think you would find these at the electrical counter/desk. If they are priced as £70, it might be worth getting them to scan it.
Forgot to mention first time round - you can cancel without penalty after four months and you keep the dish and box/remote.
