That means that, despite already paying $15 per month or $139 per year for Amazon Prime, you’ll be stuck with 1080p shows and movies unless you sign up to Prime Video Ultra.

Dolby Atmos remains exclusive to the $5 tier too.

Amazon is the latest streamer to put its prices up, following similar recent hikes to , and . If you don’t want to give the company any more of your hard-earned, you have just under a month to binge your way through the second season of  in all of its irradiated UHD glory.
