Before the end of last year, I used the AMT promo code and order a $100 gift card + 10% bonus = $110. Everything went fine. Even the final confirmation page shows $110 will be loaded to the card.

Now that I received the card, there's a slip that says "Gift Card Value: $110", but when I check the balance of the card on Marriott website, it says value is only $100. What's going on?
