A brutal story of capitalism at work: $0.75 pizza in Manhattan  

N. R. Kleinfield in The New York Times:

On Thursday evening a week ago, Bombay/6 Ave.—unprovoked, and without warning—cut its pizza price to 79 cents. The next morning, 2 Bros. retaliated by moving to 75 cents (its owners felt it was easier to make change from a dollar than at 79 cents). Bombay/6 Ave. matched the 75 cents, and that’s where everything sits.

Clearly, a slice of pizza cannot be sold profitably in Manhattan for $0.75. The price is an unsustainable gesture. Something has to give. It’s going to be fascinating to watch the story unfold.
