You probably would get better answers if you mentioned the app, but I would guess not. https://developer.apple.com/app-store/review/guidelines/#goods-and-services-outside-of-the-app https://developer.apple.com/app-store/review/guidelines/#goo...: “3.1.3(e) Goods and Services Outside of the App: If your app enables people to purchase physical goods or services that will be consumed outside of the app, you must use purchase methods other than in-app purchase to collect those payments, such as Apple Pay or traditional credit card entry.” So, I would think this app uses Apple Pay. I also remember that apps can’t make in-app purchases more expensive than other methods. I can’t find that online, though, so even if I remember that correctly that rule may have been changed.
