Do I Need an Amazon Prime Membership to Use Prime Video?
You do not need to have an Amazon Prime membership to use Prime Video.
Customers are able to purchase or rent a selection of titles from the Prime Video catalog, without needing an Amazon Prime or Prime Video membership.
Purchases from the Prime Video Store are automatically charged to your 1-Click payment method. As soon as the order completes, purchases are available to view in Purchases & Rentals.
Note: If you currently pay for your Prime or Prime Video subscription through Amazon, or through a third-party carrier, any purchases or rentals will be charged to your 1-Click payment method in your Amazon account.
If you don’t have a Prime or Prime Video subscription, if the Prime Video subscription is paid through Apple, or if you don't have a valid payment method and billing address set up in your Amazon account 1-Click settings, then any purchase or rental in the Prime Video app for iOS or Apple TV is charged to the payment method in your iTunes & App Store settings.
