Unable to use iTunes gift card for in App purchases
trying to do in APP purchase within Boom Beach and cannot use gift card credit on account
iPad Mini, iOS 8.4
The fine print at the iTunes Card purchase area of the U.S. Apple Store includes the following:
"Card may not be used to purchase any other merchandise, allowance, or iTunes gifting."
I am quite certain gift card balances cannot be used for in-app purchases.
