Lang runs a chain of health food supermarkets that offers a number of products that other major grocery retailers did not formerly carry. Lang has enjoyed a loyal and steadily growing clientele. Recently, however, he noticed that the major grocery retailers now offer several of his products, such as rice snacks, organic herbs, and oils, at prices so low that he cannot possibly match them without losing money.
