The supply of many things have gone down, the exception being drugs. And the things that are not low on supply have inflated prices.
When I was in the city (Chicago) this week my cousin and I were going to get steak or seafood and bring it back to my hotel. One of the consequences of the looting, riots, and shutdown is that in order to keep businesses running and people employed has caused the cost of food downtown to skyrocket. One of my favorite meals had been $28 dollars for several years, and was a good deal. Its not $63. The effect was less out by me, 45 miles from downtown, but still prices for even fast food have skyrocketed.
Supply and demand as always, and now, with the new administration, even though stay at home restrictions are lessened, or gone, gas is now so expensive no one wants to go anywhere. Last fall it was $1.85 for regular. Now its $3.60 where I live. In less than a year. So more and more people are ordering stuff online, including knives, ammunition, etc.
