Can someone please explain to me why the price at Gas Stations fluctuate so much.
My reasoning is the tanks, that they store the fuel in below the pumps must hold several 1000 litres/gallons of fuel, right?
When the big tanker truck pulls up, to fill them, the gas station pays the going price for that particular lot of fuel, say fer arguments sake, 50 cents per liter.
Would it not stand to reason that they can lock in their price to the consumer, until they run out and get another shipment?
