The online marketplace giant already offers a service in 28 US cities in which Prime customers can place a grocery order with their local Whole Foods store, and have Amazon deliver them their food.

And now, Amazon - who acquired Whole Foods Market for $13.7 billion in 2017 - have expanded the service to a further 10 cities, including Charlotte in North Carolina, Las Vegas in Nevada, Memphis and Nashville in Tennessee, New Orleans in Louisiana, Oklahoma City in Oklahoma, Phoenix and Tucson in Arizona, Raleigh in North Carolina, and Seattle in Washington.

The service is also expanding to more neighbourhoods in New York - where it came to lower Manhattan and Brooklyn in July this year - Los Angeles, and the Dallas-Fort Worth area.

Christina Minardi, Whole Foods Market's executive vice president of operations at Whole Foods Market, said in a statement: "It's just another way we're making it even easier for more customers to enjoy Whole Foods Market's healthy and organic food."

Amazon and Whole Foods offer a two-hour delivery service from 8 am to 10 pm for Prime members, and in August, the retail giant started offering grocery pickup through Prime Now at two Whole Foods stores in Sacramento and Virginia Beach.
