Classic Game time

Hello Gamers, Is there a way to buy a single month? Cant rlly afford to buy much gane time. A wow friend bought me 2 months for christmas and it just run out 1 hr in the new patch. Kinda desperate bc i was hyped and got catched off guard.Is there maybe another way to earn game time? Maybe some code everyjody can use once or something like that? via /r/wow https://ift.tt/6atCyZg
