I recently had SKY TV for 12 months on a half-price deal. I cancelled in December and ever since they keep sending me increasingly better offers to come back. The latest offer is 12 months half price (excluding HD Pack) plus they'll give me £100 towards my bill.
If I chose an entertainment pack and movies, I'd only have to pay about £140 for 12 months. As good as it seems, I'm gonna decline again as I just don't watch enough TV to justify the cost.
I've been thinking about getting a Freesat PVR, so that £140 would get me more than half-way to a 500gb Humax Foxsat.
