I've cancelled your existing HD for £5 thinking I'd be able to add NOW TV Boost at £3.
The propositions model I am looking at certainly suggests you can add NOW TV Boost but you definitely can't in the system.
It seems like the only option for NOW TV HD is take the HD Bolt on that gives you everything for £5:
BT and NOW TV HD Add-on
If you would like this re-instated please let me know.
Ok that is it added back for you now.
I've already asked the question to the right people to try and understand if we are offering NOW TV HD to customers for £3 or whether we bucket HD for everything including BTs channels into a £5 cost. Should find out soon enough.
I have the answer this morning.
It is by design, it is designed to be an easier experience by offering 1 HD product which gives you HD across all channels.
So in your scenario, NOW TV Entertainment HD and AMC HD (Although you might not be too bothered about AMC HD)
If you then decided you wanted BT Sport and bolted that on your package, because you pay for HD across everything, you'd also get BT Sport in HD without further cost.
