NEW YORK — How much would you be willing to pay to get those diapers within an hour or so?

In the latest salvo in the delivery wars, Target is offering same-day delivery on thousands of items for $9.99 per order through a delivery startup it purchased nearly two years ago

Until now, Target shoppers looking to receive same-day delivery through Shipt had to go to the startup’s website and pay $99 for an annual membership or $14 for a monthly membership. Those options will be still be available, but the discounter is making it easier by incorporating the Shipt feature on its website.

Target says the same-day option will cover 65,000 items and it will be fulfilled in 1,500 of its 1,800 stores in 47 states. Shoppers using Target’s loyalty card will get a 5 percent discount.

Target’s move marks the latest effort by the Minneapolis-based discounter to expand same-day options. Customers can order online and pick up the purchases at any one of its stores. Shoppers can also pick up an online order curbside at 1,400 stores. For both options, Target says the orders are ready in an hour.

Target’s moves come as Walmart and Amazon speed up their own online deliveries.

Last month, Walmart rolled out next-day delivery with a minimum order of $35 on its most popular items in certain cities.

Walmart also will be offering to have one of its employees deliver fresh groceries and put them in your refrigerator when you’re not home. The nation’s largest grocer said last week it will be offering the service this fall for more than 1 million customers in three cities: Pittsburgh; Kansas City, Mo.; and Vero Beach, Fla.
