Yes, I get it, you make more money in the long term when people subscribe.
I wish there was a global opt-out for it.
Amazon became a killer app for me (and most, I presume) due too the UIx. You clicked a button and you generally got pretty-close-to-cheapest priced product delivered very quickly.
Now it's just getting complicated, and you have to expend energy to ensure you're not getting actively ripped off by looking at only Prime items/etc.
The beauty of Amazon is that if you want to buy product X, produced in America, for a living wage, you can. You can also purchase it from a different seller where it was made in China and pay less for it. It's not the responsibility of Amazon to determine what is right for you. YOU make the choice, they just deliver product to you.
