Wal-Mart Stores Inc will test having lockers in its stores to hold goods ordered online until shoppers pick them up, Neil Ashe, chief executive of its e-commerce unit, said Tuesday.

The test is just one step the world's largest retailer is taking to link its growing e-commerce business with its thousands of stores around the world, Ashe told a group of reporters at the company's e-commerce media day in San Bruno, California.

Amazon.com Inc, which has no stores, is installing lockers in brick-and-mortar stores like Staples Inc to help customers store and pick up online orders securely.
