Hi
I have been offered a very similar deal. I walked into my local shopping centre and talked to one of the guys on the sky stand.
I have also tried to call and see if there was a better deal by going direct over the phone. Guy on the other end was prepared to let me have £5 off per month, but would not move on the price of box (also reading off a script) and I stated that it was costing me not him money to talk to him, to which he stated that if I had sky talk the calls would be free, GREAT!
Anyway the guys at the Sky stand stated they could do the box for £75 plus fitting of £60 which is significantly better than going direct. Also offered to get me money off my monthly payments if they could negotiate it at the point of order (still waiting for a response on that 10am tomorrow morning), getting it fitted week on Sat so absolutely chuffed. Shame I couldn't get it fitted for £30 but all in all a good deal i feel especially if I get some extras.
My advice would be to search these guys out, I did this in the Shires Shopping Centre in Leicester.
