I don’t know about items, by category, but in the first mad rush of panic buying in March of 2020 I was curious to see which brands of regular grocery items didn’t sell out even when others were gone. The longer they remained behind, the less appetizing they looked, and I’m talking about canned and boxed and packaged goods, not limp produce. It was as if they had “LOSER” written all over them. I imagine that rejection on that scale must have forced some product marketers to reconsider their options. One wonders if they were ever stocked again. I wish I had written some of the names down, but I was too busy grabbing paper towels, soup cans, flour, and powdered milk. (We never touched the powdered milk.)
