How do I cancel my BritBox subscription on Amazon Prime?

To cancel a BritBox subscription on Amazon Prime, one would navigate to the 'Accounts & Lists' menu on the Amazon website and click on 'Memberships & Subscriptions.' From there, select 'Prime Video Channels' where you will see a list of all video subscriptions tied to the account. Locate BritBox in the channel list and click 'Cancel Channel' next to it. Confirm the cancellation when prompted. If the option does not appear or if there are any issues, they can also reach out directly to Amazon's customer service for further assistance. It's important to remember that upon canceling, the benefits will be available until the end of the current billing period.
