Soon the big stores will close and will be replaced with Amazon.
I read Amazon’s success is due to Bezos’ realization that there were products like books that if you held it in your hands you could not tell if it had come from “Cinderella’s gold plated boutique” or “Pop’s Discount books”. Sotheby’s customer subconciously would not feel they were taking any risk buying online. His friend who started a similar business with products NOT having this quality went bust.
So there will always be brick and mortar for products folks want to touch before buying.
