How to Use My iTunes Card
Gift cards are popular as presents, and iTunes gift cards offer a wide range of choices for you as a buyer. The value of your iTunes Card appears on the face of the card. You can use your iTunes card to purchase music, movies, TV shows and anything else available in the iTunes Store.
Launch iTunes from the “Start” menu or the “Applications” folder.
Select the iTunes Store from the “Source” menu on the left side of the screen.
Click the “Sign In” button located in the upper right of the window.
Enter your iTunes account information to sign in.
Click “Redeem” from the “QUICK LINKS” menu on the column on the right.
Scratch off the silvery area on the back of the iTunes card using a coin to reveal the unique code for the card. Enter the 16-digit number in the text box on the screen. The amount of the card will show up next to the name of your account in the upper right corner of the window. When you purchase items, the amount will be deducted from your credit.
