Update: This is back in stock, if you missed it last week.
If you own an Xbox One, you’ll probably spend some money on games, DLC, and movie downloads eventually, so you might as well save 10% when you have the chance. We don’t know how long this will last, but Amazon’s currently taking 10% off Xbox gift cards in denominations of $100, $70, $60, $40, $30, and $10, with instant email delivery.
