I can upgrade from Entertainment to Big Entertainment for an extra £12.54. However, I think the only difference is the addition of NOW Cinema which I can get as an add on for £9.99. So is there any other difference and should I just get the add on? Seems odd - I would have thought BT would want to entice me to extend my contract by offering the upgrade for cheaper?
Also, I note that I pay £5.22 per month for the HD and 4K, but it looks like I can get this as a monthly add on for £5.00 per month?
