I completely cancelled Prime when they sent that email. To hit me with a monthly charge when I’m already paying a yearly fee just felt so cheap. I was already pretty unhappy with the direction Amazon had been heading; that email was the straw that broke the camel’s back.
My Amazon purchase volume dropped by 60% the following year, and another 10% the year after that. My goal is to get it down to 0, or at least in the single-digits of yearly orders.
I strongly recommend purchasing a USB bluray player + then buying shiny metal disks to feed it (or finding your public library, of course!)
Used + overstock disks are << $10. I go to the store and grab what I want. I typically leave with about 30 movies / TV seasons for $100. They're far higher quality than the content that is included with amazon prime, and typically cost about 10% as much as the "buy movie" price for the same film.
