With 4,000 U.S. stores serving as product depots, same day delivery holds great potential for a retailer with an unrivaled retail footprint, assuming a strategy can be developed to profitably unlock the opportunity.

Walmart has experimented with same day delivery on the west coast where order are fulfilled from stores and a broader rollout of the service would seem inevitable at some point in the future given online shoppers desire for immediate gratification.

Same day delivery firm Shutl will begin offering its service next month in New York, San Francisco and Chicago.

Thanks to $6 million in funding from partners such as UPS, e.ventures and Notion Capital, plans call for the firm to expand the delivery offering to 17 additional metropolitan areas later this year with the goal of enabling conventional brick and mortar retailers to realize their multichannel potential.
