I got the card April 2015 (630 FICO scores). Didn't use the Apple promotion immediately (wanted to wait until the June Apple Event). Emailed them to tell them I didn't get to use the promotion and if they could activate it again. They did. Bought an iPhone 6 and Apple Watch that June. Paid it off by November. Called them and asked for the promotion again. They gave it to me. Bought the iPad Pro and Apple Pencil. Paying that off currently. Will eventually pay that off soon and will rinse and repeat with a Macbook. No interest ever charged. No problems getting the promotion. No issues with the card.
People comlpain about the Interest Rate, fees, and charges. If you're using this card for anything other than an Apple purchase for the 0% promo, then you're not using the card properly. This is not a card you use for everyday purchases. Use it for it's intended purpose and it will treat you right.
