I'm bad on Valentine's Day but even worse on Christmas. I go shopping at nine o'clock on December 24th every year. Nobody else is there. I'm in Toys'R'Us all by myself. I get there five minutes before closing.
Like any business the oil industry runs on the basic premise of supply and demand. The more supply - the lower the price. The higher the demand - the higher price. In other words the more people who can buy oil the higher the price of oil.
