I'm a regular customer at home improvement stores, and I make it a point to occasionally just go wander down aisles I haven't been down in a while and just browse through what's available.
It's not uncommon for me to exclaim, "Oh! I didn't know THAT existed?" or "Oh! THAT'S what that's called/where to get those!". Other times it's, "What on earth is THAT for?!?" but then 6 months later I'll be like, "BRB, gotta go get one of those things."
I'm of the opinion that even people that don't own/maintain their own home would benefit from the esoteric knowledge of what can be found on the bottom shelf in the back corner of their local home improvement stores. I don't care what your hobby or passion is. If you don't frequent the home improvement stores, there's probably something there that you can repurpose for your own benefit that you'll wish you knew existed a year ago.
