Amazon to expand same-day grocery service to 2,300 cities – sinking shares of rivals Walmart, Instacart

Amazon is going all-in on its supermarket business with a massive expansion of same-day delivery of perishable items like milk and fruits — sending shares of rivals including Walmart and Instacart plunging.

The e-retail giant, founded by Jeff Bezos, announced Wednesday it will offer the same-day services in 2,300 cities by the end of the year, more than double the current 1,000 locations where Amazon Prime members can order items like milk, fruits and baked goods.

The service — already available in Manhattan and other major cities including Phoenix, Ariz., Orlando, Fla. and Kansas City, Miss. — is free for Prime members on orders over $25 in most participating cities. It costs $13 for non-members regardless of order size. 3
