I’d expect amazon to email you a receipt with an easy way to dispute payments. I realize this is not the same as seeing the aggregate cost at the time of purchase but I’m skeptical this alone will create lots of friction in ppl adopting this.

To me, the biggest thing that has kept me from trying it is that I need to open my app and scan a QR code. Looks like they’re addressing this by left you swipe your card.
