You can buy nearly everything on Amazon, including movies and TV shows. Amazon’s video storefront (not to be confused with its on-demand streaming service Amazon Prime) allows you to either rent or buy thousands of titles, including new releases, blockbuster hits, niche indies, and international gems. 

You’ll have to sign in using your Amazon account to start renting or purchasing, and Amazon allows you to redeem gift cards, promo codes, and points if you have them upon checkout. Like most video stores, Amazon gives you 30 days to start watching a rental and 48 hours to finish it, while unlimited access is granted to purchased titles. Lastly, you should know that a rented title is only viewable on one device, so sharing options will be limited. 

Plex is a media management software that doubles as a free streaming service. Its main function is to organize your own library of content—that is, your own video, photo, or sound files—and make it streamable alongside Plex’s offerings of 200+ live TV channels and 50,000+ on-demand movies and shows. Plex’s basic package comes at no cost, but it also has a premium package starting at $4.99/month that boasts additional features, such as the ability to download content and watch them offline, among other things.
