If you received an iTunes Store allowance, gift certificate, iTunes Gift Card, or promotional code, you can use it to buy songs, videos, or audiobooks from the iTunesÂ Store.
If you don’t have an iTunes Store account, you need to create one first. You don’t need to enter credit card information to redeem only the amount of a gift certificate or card. For more information about creating an iTunes Store account, click this link:
To use an allowance, choose StoreÂ > Sign In.
To use an iTunes gift certificate or iTunes Gift Card:
In iTunes, click iTunes Store (below Store).
Below Quick Links, click Redeem and follow the onscreen instructions.
The amount in your account appears to the left of your account name. As you make purchases (by clicking a Buy button), the amount changes to show how much money you have left to spend.
You can use a gift certificate only in the iTunes Store for the same country in which the certificate was purchased.
