We've seen, especially in this decade, a shift to purchasing on-line rather than schlepping to the local store for whatever. The SARS-CoV-2 virus pandemic has resulted in a large shift in this trend. In all probability, part of that shift will remain in place even if all US restrictions are lifted.
It will be interesting to see where the situation settles 6 months or so after the development and distribution of a safe and effective Covid vaccine. I believe we will not return to the sales distribution of, say, January, 2020. Rather, we'll go back to some B&M purchases but continue along the trend already in progress.
Regards, stay safe 'n well. Remember the Big 3: masks, had washing and physical distancing.
