As if the ability to watch Netflix offline weren’t enough, soon all your streaming options will change the way you watch TV. Amazon seems to be keeping plenty competitive as well, now adding the option to include HBO or Cinemax to its Prime subscription, albeit for a price.

Amazon confirms that HBO and Cinemax have been made available to its Channels selection of add-ons for Prime video members, with a caveat to your existing subscription. Both are available with 30-day free trials, after which HBO will cost you an additional $14.99 per month, while Cinemax rings up at $9.99 monthly.

Says Amazon:

HBO has produced some of the most groundbreaking, beloved and award-winning shows in television history. Their selection of blockbuster movies is unsurpassed, including hits like Batman vs. Superman, The Revenant, and Deadpool. And, our customers have been asking when all that wonderful content will be available on Amazon Channels.

Prime members can now watch the latest episodes of the critically-acclaimed Westworld and Game of Thrones without the need for a cable subscription. We’re thrilled to work with HBO to bring their cutting-edge content to Amazon Prime members with Amazon Channels.

The Channels service provides over 70 additional add-on packs for Prime video beyond the regular subscription, while the HBO and Cinemax additions offer both licensed movies and the full TV library. Granted, the pricetags aren’t too different from an HBO Now subscription, but it’ll certainly make things easier for Amazon bundlers.

As we celebrate cable’s slow demise, don’t forget to check out what you’re missing with Westworld this weekend, either.
