How do I redeem a coupon code?
In case you received a coupon code from us you can redeem it in the same way as if you would redeem an App Store gift card. Please follow Apple’s instructions: https://support.apple.com/en-us/HT201209
Please note that there are occasional problems with unlocking Premium content when redeeming coupon codes. If you are affected by this issue, please follow the guidelines of the FAQ article My Cora Premium membership is not working.
