Here is how supply and demand works when associated with fuel/oil.
When the demand is low, prices go up to maintain the ridiculously absurd profit margins oil companies make. When the demand is high, prices go up to increase the already ridiculously absurd profit margins. There is no better example of greed; greed at it's finest.
In either case, we're supplied without a courtesy reach around and left to be screwed again, and again.
I personally live too far away to commute by any other means than auto. I am also in no position to get a "beater" economy car. So, I have no option but to get in line at the gas station with a jar of Vaseline in hand and hope prices haven't gone up another quarter in the last 6 hrs. My only option is to try to find the cheapest gas (at the moment) and save a few cents a gallon without going too far out of my way.
