Ok, but checking in on twitter photos of empty shelves isn't investigative journalism, and the few people who might be in the position to know are saying its not like March 2020, e.g. "There are some issues with out-of-stocks, but it tends to be a situation where if you go to a store on a Tuesday night, maybe something's out of stock, but by Wednesday sometime it's back in store," Rose told NPR."

The point is, the article would be less sensational and more informative if it could point to some kind of systematic data source--even one they collected themselves. But they don't.
