Well, i don't recommend buying it if you are out of the US, long ago, Google has blocked the way of redeeming it out of the US, only people who are physically in USA can redeem it, otherwise you cannot. I suggest buying whether Amazon, Walmart, or another gift card from different service. Google play wil not allow you to redeem it anyways.
