The BT HD add on and NowTV Boost are separate but you can add them both and it won't cost anymore than the standard price for one at
But are telling me that to watch the Now sport as an add on in HD, I need to take the Now Boost add on, even though I have the BT HD add on, and pay for both. Meaning that I am paying £12 !
You add them both but you're only charged once, unless they've changed this
They must have changed it. As yesterday they told me I have to add Now BOOST AT £6 even though I already pay £6 for the BT HD add on!
I'm pretty sure that even though both are chargeable, you only pay once if you take both. Try putting an order through on MyBT and see what the charging structure says. You should be able to see this before completing the final purchase.
This is how BT describe it on their website (hasn't been changed yet to reflect TNT Sport)
