To watch Prime Video, an individual does need a Prime membership. However, it is important to note that Prime Video is also available as a standalone subscription. This means that one can access the streaming service without being a full Amazon Prime member, but they will still have to pay for the Prime Video subscription separately. With a Prime membership, users typically gain additional benefits, such as access to free shipping on eligible items and exclusive deals. For those who only want to enjoy streaming content, they can opt for the standalone Prime Video subscription.
