“In a competitive market, the unit price for a particular item will vary until the price reaches a point where the demand equals the quantity.   This is also known as economic equilibrium.” (Wikipedia, 2012).   This winter economic equilibrium greatly worked in my favor.   For quite some time, I had wanted to purchase a new car.   However I was not able to find a new car in my price range.   In January of 2012, new car sales were at an all-time low.   Supply of cars was way up and not enough consumers or buyers for the cars.
