Or, if you are like me, and spend a buttload of money on a limited item (demon) only for them to start selling it to everybody shortly thereafter.

Remember kids, let me be dumb so you don't have to!

There were some events with a no-qi item prize... like that event DrHax made.

How the others alreayd told you for more than 5 times, you can buy them for USD for no restriction, or you can buy them from market with no qi restriction, but from market cost 10x times more and it isn't worth.

It is because they can buy it without qi restriction (witch cost very much)
Or they buy it using USD
