“The latest location is its third overall and third in Seattle, where it’s headquartered. The 2,100 square feet store sits on the corner of Boren Ave. and Thomas St. and is its largest yet. The first iteration of the Amazon Go store was 1,800 square feet; it opened its doors to the public in a surprise opening in December 2016. The second, measuring 1,450 square feet, began doing business last Monday.”
