How Microsoft gift cards work
Xbox gift cards and Windows Store gift cards work the same way across participating stores. Give an Xbox gift card to a gamer or entertainment fan and a Windows Store gift card to friends who have a Windows Phone 8 or a Windows 8.1 tablet or PC2. Once the card is redeemed to a Microsoft account, the money can be used to buy apps, games and more at the Windows, Windows Phone, and select Xbox stores.
Your gift card never expires even after you redeem it to your account3. It’s ready and waiting to be used when you find that perfect app or that new movie you’ve been waiting for.
