You can no longer buy store permits with NX credit.

Y tho

Can't be assed to go to the store. It's so much more of a hassle than just punching in my CC# online and getting the NX charged immediately. There are plenty of publishers that are more than happy to take my CC# and then give me microtransaction credit with no strings attached. I don't see why MapleStory should be any different, and I'm definitely not going to condone this change in policy by purchasing game cards.
