Not in the business, but two things have happened in the past shortages: Hoarding and the increased demand for loaded ammunition. Loaded ammunition is more profitable than components so primers go first to ammunition production, and the loading component market gets second consideration. This time around, what is different has been the millions of first-time-gun-buyers created by the violent unrest, and these newbies are not yet ready to handload. So they just buy and hoard all the ammo they fear drives them to buy and put it aside, making the loaded ammunition market even bigger than in a normal panic buying time.
Primers don't go bad, so a reasonable approach is to assume there will be panic buying periods every few years. So, buy several slips of 5,000 when the prices aren't at panic-buyer levels, then replenish during the next buying lull.
