I guess there are too many mugs like me paying top dollar for Sky so why would they go out and tell people proactively about 60% discount deals?
They assume the majority will carry on paying the full price quite happily which is wrong I agree but it would hurt their business too much.
We had the same issue many years ago with Sky and I'm sure other companies are doing the same thing, and not making discounted rates available when clearly they are there to be offered. I understand the business logic. Doesn't sit right though
