From the Wall Street Journal comes the story of competition for shoppers. As is always the case, where there is competition, consumers win.

Four of the nation’s largest mall operators are turning their properties into mini-distribution centers for rapid delivery, meaning shoppers can ditch their bags and keep spending. The service promises set delivery times for purchases consumers make at the mall or online from mall tenants, facilitated by a Silicon Valley startup, Deliv Inc.

Macerich Co. MAC -0.46% , Westfield Group WDC.AU -2.67% and Simon Property GroupInc. SPG -0.87% are set to announce the new partnership Thursday, following a trial at several General Growth Properties Inc. GGP -0.49% malls this year. The service will be available at nine malls in Los Angeles, San Francisco, Chicago and San Jose, Calif.; operators plan to expand to more malls next year.

The move highlights how delivery has become a key battleground in the war between physical and online retailers. 

Consumers win again. When will we jettison the catastrophe that is ObamaCare and move to a consumer-driven health insurance market in which companies compete for consumers? When we do, you will see the same phenomenon at work: consumers will have more choices and more and more companies will up their game to snag the business.
