I've just enquired about getting Bt sport on sky when it launches and here is a breakdown of the cost.
£15 to register
£15 a month for the HD on one skybox
£15 a month for each additional skybox if you have multiroom.
We have 3 sky boxes in ours and all watch sport so if we want BT sport on all 3 boxes, that's £45 to register and £45 a month in subs on top of the fortune I already pay to Sky.
Cunts.
