Sky TV will also reduce their costs too roughly by a half, if you are out of contract ....just phone Sky customer services and tell them you wish to end the service, as you no longer find the monthly subscriptions value for money and could do without them.
I was paying £19 / month they asked me if I would be happy to stay for a further Six months at the reduced price of only £10. I asked "what is the catch" .?... they explained, "none, no tricks.... no need for a contract renewal and if you wish to leave within or after this concession period, you are as free to leave as you are at present."
So at least i've had the benefit of a nearly half price service for the last few months. When Six months is up, I will make a final decision whether to stay or go.
