I have noticed the same thing. I have stopped shopping on Mondays because half of the shelves are empty, at least of the most common products. Last winter heavy snow in Idaho and Southern Oregon slowed down deliveries and stores were out of everything in a couple of days.
My explanation is that stores do not want to keep extra inventory because inventory is immobilized capital that reduce dividend to investors. So they are taking the just in time delivery to the extreme. Any little snag in the delivery system, and the shelves are empty.
It is just another way to make investors richer at the expenses of rest of us. A weak infrastructure makes a country weak.
