Amazon announced plans to close all 19 of its Fresh supermarkets in the U.K. as it focuses on online delivery growth. Five Fresh locations will be converted into Whole Foods stores. The move comes as Amazon recalibrates its grocery strategy to emphasize online sales over physical stores.

Amazon CEO Andy Jassy remains optimistic about the company’s grocery business, highlighting the success of online sales for everyday essentials. The company also plans to offer same-day delivery of groceries, including perishable items, in the U.K. starting next year.
