Could there have been local factors involved? In my area the only ones I recall were TP and some cleaning supplies.
Recall that there was mass “lock-down” everywhere, for everything. No one was supposed to work.
TP and cleaners were the big thing. But also I have pix of the missing food.
Further, guess what? The cleaner manufacturers went to “war-time” footing as e.g., Clorox stopped making Scentiva bathroom cleaner (I like it better than Scrubbing Bubbles), 409 stopped production, etc. Many decided to only make what was super important - esp. for the dreaded COVID disease itself, or send it to the hospitals only. I still cannot get Scentiva but thank God, finally this year 409 is on the shelves again. (I bought Clorox general purpose after 409 disappeared.)
This hysteria hit hard, and we’d better not forget this little lesson in what it’s like to have socialist rules ruining everything. Another step toward getting us all used to it, because it’s “for a good cause” (like the rioting BLMers).
