Beyond the Google Play Store landing page, Google also made the help page live too. It goes over the basics of how to use a gift card and how to redeem it. It also lets you know that the gift cards are only available in the U.S. for the time being. The cards may also only be used for purchases that are listed in dollars. So if you take your gift card and ship it to a buddy in Germany as a present, he can’t use it because everything there is in euros. Similarly if you go visit your buddy, you can’t use it either. We assume that any country that uses U.S. dollars as the currency shouldn’t have an issue though.
With the cards on the shelves for purchase and the landing and help pages up, all that is left is to activate the service in the Play Store. Bet we see that update hitting devices extremely soon. We would guess that it is probably already being pushed out now, but we haven’t seen it yet. We will keep our eyes peeled for it though and let you know.
