Except even then, they could just list both the real money cost and the in-game points cost. There’s no need for the points to be tied to the real money at all.
What if I want to buy something that costs 1000 points, which equates to $10, and I have 300 points in-game? I want to use those 300 points, but I want to cover the rest with $7 of real money. If they only list two costs - $10 or 1000 points - I can’t do that, but if they let me buy 700 points for $7, I can do it.
