App with both Digital Subscription and Physical Goods

We are making a design app where users can create designs, and then use those designs to print a T-shirt with that design. We are thinking about subscription model, where a user pays $49/year to access that design tool. With the yearly subscription, they will receive $10 credit toward making a T-shirt. Our terms would like to make the $10 credit contingent on keeping the yearly subscription.

Consider this scenario: a user subscribes to app through the app store, and immediately uses the $10 credit for the physical goods, and then requests a refund for the app through reportaproblem.apple.com. In this case:

  • are we able to charge them $10, or
  • will they receive a full refund and we will have to pay the $10 cost ourselves?
