They have an app on Samsung TVs
Just used this. Although I have used their offer, still got 3 months out of it! Heat
BFI Is excellent but its only MAJOR drawback is that there is no actual app available that you can use on a Smart TV or device such as Amazon Fire Stick or 4K Stick, I tried all-sorts and find the ONLY way to really enjoy this at its best is to watch on a PC which is not ideal really, still I FINALLY managed to bookmark the main player page website in Firefox Browser on Amazon Fire Stick and watched that way, but the BFI Channel is actually available on the Amazon Platform but sadly you cannot use any BFI vouchers redemption codes via the Amazon Channel.
You can sign up at Revolut and use a virtual (burner) visa card for stuff like this. (y)
