Have you ever wondered why gas was priced with 9/10 the of a cent per gallon? The answers are varied but it appears that back in the day when gas prices were a whole lot cheaper the oil companies used this tactic to make a little extra on each gallon. when the consumer looks at the price they do not notice the 9/10 and back when a cent was worth something it amounted to a nice profit. Nowdays the impact is a lot smaller and to the consumer who uses 500 gallons of fuel (Average usage) tht amounts to $45. $45 I could use for something else for sure. Studies have also found that when a price ends in 9 consumers buy more. And gas prices always end in 9. The oil companies get an extra $150 to 200 million dollars a year from this pricing. That is just a drop in the bucket to them. I have been trying to figure a way to get this pricing system changed. It just does not seem right that they post a price odf $2.999 a gallon and charge me $3.00 a gallon. I am still working on it, maybe the Commerce department is the place to go.
