Gordon, I was reading your reply and was thinking "DEMAND... Yeah, but what is the strategy to find it?"

And got this idea: type the word "looking for" at Facebook Marketplace.

And there are there ADS from people who are LOOKING for stuff.

And even we can choose the price range.

For the most stuff that appears is LOOKING FOR ROOMS FOR RENT and CARS. Not the type of products that I want. I want small trickets, maxim 20€.

So, if I see many identical products with the title "LOOKING FOR"...

Smells solid like there is DEMAND.
