Although most channels have a monthly cost, Prime Video does include the ad-supported Freevee channel for access to a number of shows and movies for free. The channel includes popular movies like "Now You See Me" and "E.T.," binge-worthy series like "Mad Men," and even original shows like "Leverage: Redemption." 

In addition to on-demand content from Freevee, Prime Video also has a few specialty livestreaming channels for free, including Crime 360, Tastemade, and Filmrise.

Since these channels are all free, however, they include commercial breaks.

You can find all the Prime Video channels here. At a glance, the complete lineup includes over 150 channels to choose from — ranging from Discovery Plus and Starz to Shudder and BritBox.

Most channels on Prime Video cost about $6 to $15 a month on top of your existing Prime membership. You can test many channel subscriptions with a free seven-day trial before committing.

In most cases, Prime Video Channel prices are the same as what you'd find when subscribing directly to each standalone service. But signing up via Prime Video offers members the added perk of keeping all their subscriptions housed in one platform.
