Predatory Price

In business and economics, predatory pricing is the practice of selling a product or service at a very low Price, intending to drive competitors out of the market, or create Barriers to entry for potential new competitors. If competitors or potential competitors cannot sustain equal or lower prices without losing money, they go out of business or choose not to enter the business. The predatory merchant then has fewer competitors or is even a de facto monopoly, and hypothetically could then raise prices above what the market would otherwise bear. -- http://en.wikipedia.org/wiki/Predatory_pricing
