How do I watch a movie and pay on account

[Csowerb]

I want to watch. Movie but it's asking me to pay with credit or debit card. I want to pay through my account and can't find how to link account ?

Hi @Csowerb 

If you are buying / renting from Skystore online or on the app you always have to pay by card. No
option to add it to your Sky account. 

If you are buying on Sky Q then the cost is added to your monthly Sky bill. 

what platform are you using ?
