Yes I’ve noticed an uptick in things that a prepper might be interested in. Mostly not directly or specifically marketed as such.
But conspicuous by inclusion in the general merchandise. Usually because of its size, storage life, or dual use.
Then there’s the specifics for my area anyway. Winter storm season is a big time marketing of things like generators, long term storage food, batteries, and more.
Tag lines of “Be prepared!” And “Protect Your Family” have crept into the ad copy.
