I have mixed feelings already about Prime Video, as a watching experience I find it quite annoying because I'll find a movie I'd like to watch only to find I have to pay another $5 to watch it. With the other services, I know if a movie comes up on the display, I can watch it without further cost.
I'm fairly sensitive to adverts, I really don't like seeing them, largely because I've isolated myself from them. The fewer you see, the more unsettling they are, the blatant attractive factor of them, do.not.want. And anther $40/yr is too much.
Apparently, dropping Prime with the shopping really does not impact the speed of delivery or cost. I'm already often selecting delayed delivery. With the increased prices, it's hard to justify the $140/yr.
