May be a bit late but if you have not made the move yet, try ringing up and tell them that you want to leave Sky (assuming your no longer in your initial 12 months contract).
The retentions dept will jump through hoops to keep you and this may well include a vastly reduced price for the sky+ box and/or free fitting.
The cheap prices that you see are for new customers, us existing custo...mugs have to pay full price
