I really can't argue the figure, I don't know. The 9 cents a gallon was what was put out on his show and I've read several threads here that quoted 8 and 9 cents a gallon profit. That does seem high to me because there's an awful lot of gallons sold daily.
I did a search and
this one was the easiest find. It says 11%. There was some other threads that posted various raw numbers from different sources-sales and profits. That's where I got 7%, some got 9-10%. Still 11% of $3.00 is 3.3 cents. Seems the 9 cents should be 9%. Gas doesn't cost $1/gal. Most news stories attempt to obfuscate and overwhelm with huge profit numbers. None mention sales and few give an accurate, if any mention of what the profit/gal is.
