Covid is keeping a lot of people home, and they are ordering stuff on line. Amazon is busy now, and probably figures this behavior will continue well into the future. Check on delivery services, they probably need help. One man I know is waiting for action on a contact tracing job for Covid victims.
Even with the delays, I think millions of people who never online shopped before will continue doing it for now on because it is so convenient. Also, it is so easy to return something you don't want. They pay for the shipping and everything and give you no hassle about it.
Not just Amazon but other companies like Zappos, NewEgg, LL Bean, etc., are doing huge business through online shopping.
I don't see brick and mortar retail going completely away because people are always going to want to see and touch the product. But I see many stores downsizing and having minimal product on hand. For instance, when buying a TV, you look at what they have, choose the model you want, and the product is shipped to your house from a central warehouse. I see same day delivery for this in the urban areas. So by the time you get home from the storefront, your product might be waiting for you on your doorstep.
