¹ it was a bit of a mess, they first tried to bill an empty credit card, but only notified me after several attempts when prime was actually suspended. I added a regular credit card, but they don't conform to the new EU rules about authentication so it just got declined. Again, they didn't tell me they were even trying. So I added a SEPA account which is possible through the UI, but apparently they required a credit card. In the end I just cancelled, and re-signed up under the amazon of the country I live in (which is fairly new, hence not doing it the first time.) At least I get another free trial month for the hassle.*
Just the fact that I–a software engineer and longtime Amazon customer–felt compelled to open a new tab and Google questions about the cancellation process, seemed ridiculous to me. Plenty of less tech savvy folks are sure to have been confused, tricked or given up in the process.

When I found myself slowly buying fewer things on Amazon a few years ago and decided to cancel Prime after many years as a subscriber, I was so grossed out by the cancellation process that I’ve actively avoided ordering from them ever since.
