Another thank you here for the Sky test.
We also received a bill for £66.25 and I phoned them to see if it could be reduced as there are many channels that we never watch.
The documentary channels, kids channel and the stop/start record function were great favourites.
We rarely watched movies, never watched sport and I felt that many of the high definition programmes were pretty bad content wise.
The woman that I spoke to at Sky re the bill was lovely, ask me all about her granny, children, hobbies, go on, ask me....at the end of a long conversation, she told me to look at the Sky website for info. 
£795 for a year is a lot of money and even the lesser packages are a lot so we will not be subscribing.
naturalbaby - that is a coincidence - we never received the first letter either, just the billing one.
