Since it is Amazing Aces birthday I would like to thank him for being a great friend and a a Armored Vehicle Expert! I will gift him with a $25 Google Play Gift card but the problem is, he doesn't know what it is and how to use it. I tried telling him, but I am not sure if he knows how to use it. Could someone please explain in detail, how to use it and how he is able to redeem it on his android phone. Once again Happy Birthday Ace!
