I have a prepayment card (I load it up with euros when the exchange rate is favourable) that I've had for years and use when we go into Europe. I have a vague recollection that a few years ago a large number of businesses in Europe were in revolt against Mastercard, the provider of my prepayment card, over excessive fees for transactions. Something like that. We were temporarily worried that it would make our card almost useless, but in the end it got resolved, possibly by Mastercard lowering its fees?

But Visa vs Amazon...a war between two bad boys, like most wars...

We breathe the polluted air...
