First week on the game and I am loving it. I was going to get my subscription going for after the 30 day free period....but for the life of me I cannot find out how to. Not real sure why a company makes it so complicated to give them money lol. I looked at Target and Walmart for game time cards and found none, and all I have come across is this Crysta or something, but it didn't say how much I need per month or how to go about getting some (Only examples I found were for EU, and I am in NA.

Any help on this would be appreciated so I can get the ball rollin before the month is up. Thanks in advance
