These sales you mention may help Coscto, Home Depot, Sears, etc, but it won’t really be going into the SD economy. I know a few people who will be out of work for weeks. They won’t be compensated. This is lost income. Businesses in SD have shut down for a few days. Commerce has halted in many cases, and may remain slightly slower for a while. All I’m saying is that the gains you can see easily, are easily countered negatively by losses that are harder to see.
BTW at least one Costco had to close its doors for a day or two. They usually sell $800k per day. It effects everyone.
