Amazon is eliminating its fee for grocery delivery in the United States as competition heats up in the rapidly expanding food delivery business. Tuesday, October 29, 2019, grocery delivery from Amazon Fresh is free for Prime members who have previously used the grocery-delivery service.

Amazon is rolling out the new, free service in phases: Prime members who haven’t yet ordered groceries can request an invitation. Amazon didn’t say when it will start taking on new grocery-delivery customers.
