If I was to set up a shop where the sellers input their own price for their items, is there a way to implement this given that Apple only has tiers available with increment? Apple only allows for XX.99$ amount and then starts jumping by interval. If there was a seller than wanted to sell a shirt for 31.10$ (or 12,305.37$) by example, is there a way to do this? I am trying to find a way to move away from the tiers given the way I am setting up my app for sellers to input their own price. What would be a work-around, am I missing something? I was looking to implement something like this with StoreKit, but I am flexible to move to another product for anything that would make this possible.
Does this apply in your case?
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.
