Spend $5 or more, get $5 back
Get a one-time $5 statement credit by using your enrolled Card to spend a total of $5 or more on iTunes by 8/31/2015.
Offer valid only for iTunes, App Store, and iBooks Store purchases made through iTunes. iTunes gift cards purchased in Apple stores, on Apple.com, or through a 3rd party are excluded. Not valid for purchases of any other Apple products in-store or online at Apple.com. Must add offer to Card and use same Card for one or more transactions in order to redeem. Enrolled Card must be set as iTunes payment method in order to receive statement credit. If you receive a replacement Card during the offer and use that Card to enroll, you must update your Card on file with iTunes prior to your purchase to receive the statement credit. If items are ordered during the offer period but are not provided until after 8/31/15, those items may not count toward determining whether your purchase qualifies for the offer. Enrollment is limited. Offer is non-transferable. Limit 1 statement credit per American Express online account. Statement credit will appear on your billing statement within 90 days of 8/31/15, provided that American Express receives information from the merchant about your qualifying purchase. Note that American Express may not receive information about your qualifying purchase until all items have been provided by Apple. Statement credit may be reversed if items are returned/cancelled. If American Express does not receive information that identifies your transaction as qualifying for the offer, you will not receive the statement credit. For example, your transaction will not qualify if it is not made directly with Apple. Also, in most cases, you will not receive the statement credit if your transaction is made with an electronic wallet, through a 3rd party, or if the merchant uses a mobile or wireless card reader to process it.
