I’ve had Amazon Prime for a number of years in order to have content to stream, and apps to download, to my various Kindle Fire tablets. The price is currently $99 a year plus tax, it’s going up this year whenever your current yearly subscription comes up for renewal, to $119 plus tax. (There hasn’t been an increase for four years and they say shipping costs are going up - free two-day shipping is also included and I use that also, so I can accept the necessity of a price increase.) I go with the services that interact best with my devices. BTW, I also have an antenna for my HDTV that brings in about 20 local channels and substations plus two religious channels, all for free. For sports, I’m at the mercy of what is streaming free on the internet.
It’s amazing what a good antenna setup brings in for free!
