My theory on the TP "shortage" (which is not actual, just on consumer shelves).
In everyday pre-COVID-19 days, most people spent more than half their waking hours away from home.
Point 1- Waking hours is the time when TP is most likely to be used.
Point 2 - Many people are spending all their waking hours at home
Point 3 - Most businesses use predictive ordering based on average usage. Most homeowners buy TP (and most other products) when they are getting low, or are afraid they might be getting low.
Therefore, with more people being home, with their Just in Time inventory management, store shelves tend to be low/out because much more is going Direct To Consumer.
FWIW, we have not had any trouble with our normal/conservative re-order policy/procedure.
