Amazon is extending its one-hour Prime Now delivery service to cover goods purchased from select third-party stores, with the service launching today in Manhattan for a trio of upscale shops. Subscribers to Amazon Prime can now order groceries, baked goods, and prepared meals from D’Agostino, Gourmet Garage, or Billy’s Bakery — with their shopping then delivered via Amazon's couriers in less than an hour.

"Whether you’re ordering diapers or fresh produce."

"So whether you’re ordering diapers and a big-screen television from Amazon, fresh produce from D’Agostino, a chef-made prepared meal from Gourmet Garage or cupcakes from Billy’s Bakery, we will get all of the items right to your door in lightning-fast speeds," said Dave Clark, Amazon’s senior vice president of worldwide operations. "We are launching delivery from local stores through Prime Now in Manhattan today and will add local stores in other cities where we offer Prime Now soon."

Customers can order from the Prime Now app on iOS and Android, either choosing free, two-hour delivery, or paying $7.99 for the one-hour option. Following today's launch, Amazon says the next stores to be included in the scheme will be Italian marketplace Eataly and Westside Market. The company's choice of stores shows they're not trying to cater to Walmart and Kmart customers, but if you're a Prime customer in desperate need of a $42 batch of banana Nutella cupcakes, why bother leaving the house?
