When it's not busy sending its delivery personnel on the New York subway, Amazon has quietly been working to expand its one-hour delivery service. From today, customers in Manhattan, the company's first Prime Now location, can shop at a number of local businesses and have fresh food delivered within 60 minutes. D'Agostino, Gourmet Garage and Billy's Bakery are the first companies on board, offering groceries, cooked meals and freshly baked cupcakes respectively alongside Amazon's own range of goods. The online retailer is starting small but plans to add more stores across Manhattan over time, with Italian food market Eataly and Westside Market already waiting in the wings. As before, Prime Now's one-hour deliveries cost $7.99, so be sure to factor that in before impulse buying those delicious treats.
