I havn't been with Sky for a couple of years now. But still have the old box. I have heard people on HUKD who have been discounted packages, so i thought i'll try myself. I rang sky an spoke to a bloke who said he could offer me half price for 6 months. If i kept my old equipment, this worked out at 20.50 a month & no contract so i can cancel even after the 1st month. If i wanted to upgrade my box, it would be £60 for installation and £30.50 for my package. Hope this helps somebody.
