I'm surprised at how few retail websites have implemented Apple Pay for checkout. It's a pleasure to use a site that implements this and when they do I'm happy to buy directly from them instead of through Amazon. Sites that make you manually enter all your shipping and credit card information while navigating thru last minute check out popups is a big reason why it's so much more convenient to buy the same thing thru amazon.
There are a lot of things we can do to improve the web and make it more resilient to big tech. Optimizing web sites for rapid checkout with modern Apple and Google pay mechanics is one of them.
