Nexon Karma Koin $25
Good but could be easier to get.
It's a game card so there isn't anything to complain about there, it does it's job. My only gripe is that it is annoying it doesn't have an online option apposed to going to a store that may or may not have it there just for a game code for an online currency.
It's good, but it needs email delivery.
It would be a lot more convenient for this product to be available online for email delivery. Aside from that, it is a good product.
