Profit margin depends on what you claim as your 'cost'. I've worked in the energy industry for 20 years, and realize what a joke it is when oil companies say they are only making a 10¢ 'profit' on a $3 gallon of gasoline. It's because they control internally what they call 'costs' like transportation, refining, marketing, advertising, distribution, etc. When they artificially inflate those 'costs' they can say that their 'costs' are $2.90, when in reality they are internally retaining $2 - split between/within the production company, the refining company, the pipeline, the gas station, etc. Poor guys, only making 10¢ on a gallon of gasoline. Yeah right. And Wilson has the smallest profit margin in the industry.
