Discontinuing Ultimate Game Card Support

...WHAT. How much does Nexon earn off of each card, then, if Walgreens is willing to discount them? :l

Also,

That's pretty simple: Total cost to nexon per card: 20 cents tops(?) since they're likely to be mass produced. If someone sells them for 10 dollars normally, or even discounts them to 5... then they still make a big profit... not as big as the full price, but it's still a profit.
