WAL-MART'S SAME-DAY DELIVERY SERVICE: Wal-Mart is testing a same-day delivery service in select markets for customers who buy popular items online during the holiday shopping season.

WHAT'S BEHIND THE MOVE: The news comes as the world's largest retailer faces increasing competition from online giants like Amazon.com., which is also testing same-day delivery service in 10 markets.

THE DETAILS: Wal-Mart's tests started this month in northern Virginia and Philadelphia. The program rolled out to Minneapolis on Tuesday. It plans to test the service in San Francisco and San Jose, Calif., later this month or in early November. .
