Go back read and think about the original question then get back to me if you would like. You may also want to look at the discussion w/ Dangus.
You have not made your case. This is a matter of a station trying to make a profit. As everyone who has ever been in a position of bottom-line responsibility knows, you do what you can to make your profit projections.
I am not saying, however, that you'll never see a case of price gouging at the station level. We had one right here in my town on September 12, 2001. I haven't done business with that station since.
