An Apple App Store & iTunes Card is a digital code for an eligible Apple account. This entry is marked USA. Check the card type and permitted uses; an App Store & iTunes card should not be assumed to cover Apple hardware purchases.
Which denomination should I choose?
Select the Apple App Store & iTunes Card value and currency shown in the offer. This is a digital gift-card or balance-code purchase; it does not promise a fixed subscription term unless the offer explicitly states one.
Does the catalog region guarantee compatibility?
No. Check the specific issuing country, currency and account eligibility in the offer. A broad label such as Europe or Global is not a promise that a code can be redeemed in every country.
