Can you elaborate on this, because this is what I understand (from the point of view of someone who knows nothing about Apple's review process):

You can't provide your app at no cost on the App Store. You can't provide your app for a cost on the App Store, if you don't include in-app payments.

Or is it the case that you want to allow your customers to make nominal purchases through the app, and Apple say these must be processed through in-app payments?
