NEW YORK—Walmart is rolling out free next-day delivery on its most popular items, increasing the stakes in the retail shipping wars with Amazon.
The nation’s largest retailer said on May 14 it’s been building a network of more efficient e-commerce distribution centers to make that happen. The next-day service will cover 220,000 popular items from diapers and non-perishable food items to toys and electronics. That’s nearly double the number of items it carries in its stores.
