Hi Fahoudi,

Click this link and redeem your Apple Store Gift Card:

You can also contact this number:

By calling 1-800-MY-APPLE.

Your Apple Specialist will need the PIN (located under the scratch-off surface on the back). Remember to keep the card until you receive your item(s).

Be sure to sign to your Apple ID.

Cheers!
