It depends on the lived environment. In my US suburban house, a 20 minute drive from the warehouse/Costco, absolutely. In the Spanish town I am in, where I can do 10 errands in an hour ln foot, as basically every street level space is a store, and streets are themselves narrow, Amazon's logistics advantage loses to the Asian bazaar.
Costco's Spain operation is primarily for logistics and product test, not market penetration.
Costco usually tests suppliers' packaging and logistics for products at their ExAmerica warehouses before deciding on exporting that vendor's product to NAM.
This is how Costco became the largest alcohol exporter in Europe, why most frozen fish at Costco is soured from Iceland, and how Chinese, Japanese, and Korean goods and vendors are tested before selling at Costcos with large Asian American populations.
