Target is extending its next-day delivery of household essentials to eight more major markets, including New York, Los Angeles and Atlanta.

In mid-October, when Target Restock expands to the San Francisco metro, the service will reach more than 70 million people in 11 major markets, or about one-fifth of the U.S. population, the company said Thursday.

The service launched in the spring in Minneapolis. Dallas and Denver were added over the summer. Also added Thursday were Chicago, Philadelphia, St. Louis and the Washington, D.C./Baltimore areas.

Target Restock leverages Target's store network to get digital orders packed and shipped swiftly.

It's one of the latest examples of how Target is combining stores and digital with the aim of making shopping more convenient for customers — and competing against Amazon, in this case its Pantry service for Prime members.

Target Restock allows online customers to pick from a list of 15,000 household items to fill a box, which is delivered the next day for $4.99. The products range from personal care and baby items to cleaning supplies. The weight limit is 45 pounds.

"Guests need to keep daily essentials stocked, but finding time to buy them is tough — and it can be even more of a challenge when you're talking about large, bulky items," said Dawn Block, Target senior vice president of digital.

"If we can help our busy guests check off their shopping lists quickly and more easily, that's more time they can spend with their families," she said.

So far, popular items in the Twin Cities, Dallas and Denver have been on-the-go snacks, beverages, cereal, macaroni and cheese and paper towels.
