To redeem an iTunes Gift Card:

1. In iTunes, click iTunes Store in the Source list to go to the iTunes Store homepage (if you're not there already)

2. Click Redeem under QUICK LINKS in the right column.

3. In the resulting screen, enter the entire code in the field

4. Click Redeem. If you aren't already signed in to the iTunes Store, you'll be asked to sign in (see "Set Up an iTunes Store Account http://docs.info.apple.com/article.html?artnum=304672”, if you need to create an Tunes Store account ID)

5. Once you redeem your iTunes Gift Card, the full amount appears next to your account ID name in the upper-right part of the window as a credit. Any time you buy an item, the purchase price (+ tax) will be deducted from the balance
