This is not at all surprising. We got rid of prime about a year ago and generally have avoided buying through Amazon, but on a few occasions, it's been the only option so we bit the bullet. It was awful.

Prices and shipping listed were for prime members (autoselected of course) with small print nonprime member prices selectable. Their once famously easy purchase process was multiple screens full of "don't you want to rejoin prime??" pages with the option "join" already checked. Even after selecting the nonmember price and saying no to prime, going to the checkout page revealed an option auto checked for 'faster shipping' that was actually an option for rejoining prime. In buying multiple items this was autoselected on each of them separately, so you're agreeing to prime if you miss changing one.

Even if I have to order from them periodically (which I avoid like the plague), I have no intention of paying for prime again. The whole purchase process is an indicator that dropping prime is making an impact and I want that message to sink in.

For those who have Alexa, downgrading the plan, or even better-- finding an alternative home assistant, will send an equally powerful message, even if Amazon isn't ready to hear it.
