I will echo what Grey said. The OTC meds is a big one. The food issue is a wobbly one, but I would err on caution and stock up.
There is concern about the combined Flu and COVID season (in fact i just heard the "word" Fluvid today for the first time). Signs and Symptoms of Flu vs The Vid are nearly identical, so it takes testing to differentiate. But even with testing we can fill a hospital with either. COVID does not have to be bad to shut things down. Remember the Flu spreads pretty easy as well and with more and more ignoring the flu shot it can spread quicker. So two schools of thought, the general mask wearing, social distancing will help the flu season or if things go even slightly sideways, the combined Flu and COVID patients in the hospital WILL be a huge problem, enough to shut it down again.
