Absolutely, more than happy to :-)

Amazon is currently able to invest $100M's and 100s of engineers into perfecting the checkout experience. There are actually hundreds of things you can do to optimize checkout. Here's one study: https://baymard.com/checkout-usability

We do all those things. We invest the engineering resources to perfect checkout. So that you don't have to. Even our checkout today is not perfect, but it's way better than the one's we replace. And will continue to improve with every deploy.

Now that you say it, Amazon-like can be a bit confusing. Really it appeals to our vision to help every online business compete with checkout by optimizing their payments flows.
