Hi @dihetherington
I went through the process last week - adding NOW Cinema to Big Sport.
1. Log into MyBT
2. Click manage Your products
3. Click manage TV and Sport
4. You will see the TV package you are on. Click on Swap your package. [Don't worry nothing bad will happen as you are given the option later on to confirm or to cancel]
5. You will see options to switch your package. Ignore that, instead click on Manage add-ons further down the screen.
6. You will see options to select various add ons including NOW Cinema.
All the add-ons are on a monthly rolling contract (not 24 months). When you don't want NOW cinema add-on any more repeat the process and switch it off.
Regarding your question about whether the Entertainment package will be £6 if you switch package and then back to Entertainment. I would contact BT directly to ask. I don't think anyone on this forum has been through that process so can't advise you definitively. For example @Bluemoon1 reckons £6 would still be available. if you switch and then switch back, I on the other hand think it is a time limited offer so Entertainment would be £17. But we're both speculating - check BT before switching.
