Walmart testing same-day delivery

The service is only available through the holidays and in only a few locations - Philadelphia and Northern Virginia started last week and SF and San Jose will be added later this month. Called Wal-Mart To Go, it costs $10 regardless of order size. Orders must be placed in the morning. Amazon recently began testing same-day delivery in a few cities, including SF, and with its new distribution centers in California it's likely the service will expand. The same-day movement, while intriguing, is not inevitable: Or do you forget the online grocers in the 1990s that struggled with making deliveries? It would be especially hard in Socal. From the WSJ:

Instead of shipping goods from its football-field sized distribution centers scattered across the country, Bentonville, Ark., based Wal-Mart will pluck products from its vast network of more than 3,000 "supercenters." United Parcel Service Inc. UPS -0.88% will pick up the goods and deliver them to customers, who have until noon to place orders and can choose a four-hour window in the evening to receive deliveries. The service doesn't cover groceries.
