Apologies if this has already been posted, but I see Sky are running an Introduce a Friend offer where both parties get a free Sky+ box. The existing customer pays 60 installation and the new customer pays 30 installation. But what they don't advertise is that you can upgrade to Sky HD instead of Sky+ by paying 99 + installation. That represents a saving of 150 as against the normal price I was quoted of 249. You still pay the extra 10 a month though.
