I was thinking the same thing when I saw the title. But, my next thought was: what a reasonable profit margin before it's considered "over charging"... 20%? 50%? 100%? 200%? Is that even the right way to look at it? I mean, perhaps some company is providing enough value and enjoyment of their product that a 500% profit margin is gleefully paid by their customers.
