I got the letter this morning too. Bit late!
A letter arrived today for me about the offers.Funny how they send them out so only a week left to view them,its almost Sept.
I didn't get a letter for this but did get 1 other week about it going upto £55 a mth - growl.
Good find :) We only have sky+ (and have only just got that!) but will pass this on to anyone I know with HD
do you just order them as per usual and wont be charged then? does it say available to all sky hd customers?
