If you or I had to arrange the installation ourselves (i.e. with Sky having no part in the process), then it would cost more. In the same way that if you went and bought the dish and box from a shop, it would cost a lot more than it costs Sky. When Sky provide you with the installation/box for “free”, they are doing so at a lot less cost to them than a member of the public could arrange themselves. You can’t liken “high street prices” to the significantly lower “trade prices” (call it what you will) that Sky pay out.
And I’ll say for a third time, I am not asking for Sky to drop their prices. I’m long over the fact that I can’t afford it, but this does not detract from the fact that what Sky is offering is a terrible deal. And if you care you read my previous thread, I don’t even blame Sky for it (at least not totally). The Sky deal should never have happened, and I lay the blame very much at FOM’s door for that. I don’t like Sky, but one can’t deny that they’ve got a good business, which is after all their main goal.
N.B. I’m not a Sky technician, however Sky claim on their website that “[set-up] shouldn’t take longer than an hour”. And I believe I’m correct in assuming that this means that installation takes less than an hour in most cases.
