Watch Movies on Amazon Prime

For one flat-rate annual fee, subscribers to the Amazon Prime service get free shipping on a wide range of products. They also get free borrowing from an extensive library of ebooks, and unlimited listening to a collection of more than a million songs. One of the most attractive benefits of the service is unlimited access to a catalog of over 40,000 movies available for on-demand streaming. That makes it easy to watch Amazon Prime movies online.

The Amazon Prime Instant Video catalog of movies is intended to compete directly with those of streaming services such as Netflix and Hulu Plus. Of the 40,000 titles in the Amazon Prime catalog, about 15,000 of them are feature-length films. The movie offerings range from classics to recent releases like "Star Trek Into Darkness" and Joss Whedon's "Much Ado About Nothing". About 10 percent of the movie titles are available in HD format .

A one-year membership to Amazon Prime costs $99 - which translates to $8.25 per month, as compared to Netflix's $8.99 basic monthly membership fee. It includes unlimited streaming of all the titles in the Amazon Prime Instant Video library. Unlike other streaming services, however, Amazon bundles its video offerings with a package of additional perks. They include music streaming, ebook lending and expedited shipping services.
