Sadly, there's no 30 day option cards. The time cards, which is what you want to add more time, only come in increments of 60 days which is two months. You're only allowed 180 days max. So if you can add 60 days without hitting the 180 day cap on your account then you can do it. If you're at cap or still not low enough to add 60 days then you have to wait 2 months game time to then be able to add 60 days with a game time card and get your outift. I'm in the same boat this is how I know this lol Can't get mine till May
