Rill is not a store. There is no cart and no app store.
You pick the link that promises the result. You pay that link. You use what comes back.
The link is the thing you are buying. Not the company. Not a category.
A page that only talks about the product is not a pay link. Ready means the link can actually take a payment.
If you pay twice with the same request, you get the same result. You are not charged again.
