Sky pay once watch forever offer

[badboy147]

Well i called sky and had to keep pestering them that i would leave my other hd subsciption if they didnt help me get the 4 months subsciption.
They transfered me after 10 mins to there contract supplier and he said to me in order to recieve this you will have the 4 packages and thats it. I said if i could get a offer because i am a subscriber to sky and i pay £58 monthly for sky. They offered me HD for £20 extra which i was happy to have. There was a £10 charge to install everything. I had a spaire HD box which they paired it up with. They ONLY give you a standard box. Im getting £10 off my HD subsciption because i have two sky subscriptions.
