What a strange piece of fluff.

Amazon wins because of convenience (don't need to leave the house, park your car, carry stuff), variety (no b&m store can compete) and often price. Those who shop online will never switch back to conventional stores for the same needs, but there will always be a niche for brick & mortar stores where the type of products or customers is no good fit for online shopping.

These are 2 separate, established channels now and neither can completely replace the other, but online shopping will still kill off many more brick & mortar stores.
