By Arriana McLymore NEW YORK (Reuters) -Subscribers to Amazon.com's Prime service can now get strawberries, milk, meats and frozen dinners on the same day they order them as the company expands its fast-delivery option to perishable food items,

Amazon AMZN will broaden its grocery delivery offering to reach more than 2,300 cities and towns in the U.S. by the end of the year, the e-commerce giant said Wednesday. Amazon stock gained while shares of a rival, Instacart parent company Maplebear CART, fell sharply.
