I started buying the "annoying to list" stock everyone else skips and the thinner competition paid better than the easy stuff

For ages I had a reflex I didn't even notice. In a charity shop I'd pick something up, realise it'd be a pain to list — no brand, no label, some technical thing with ten specs, a garment where I'd be squinting at the wash tag for measurements — and I'd just quietly put it back down. Too much faff.

Walk on. Then it clicked what that reflex actually was: not a signal the item was bad, a signal it was annoying — completely different things. And everyone else has the same reflex.

Every other reseller is also putting the fiddly stuff back for the same reason. So the hard-to-describe items are structurally under-listed — fewer people bother, so there's less competition, and what does get listed is often under-priced, because the few sellers who list it aren't fighting each other on it. The difficulty of describing it was creating a supply gap.

And the only reason I was walking past that stock was the describing — not the item, not the demand, not the margin. So the moment describing it dropped from ten minutes to a few seconds — photo in, full listing out, specs and all — that barrier evaporated for me while it stayed firmly in place for everyone still doing it by hand. So I flipped the reflex: instead of avoiding the awkward, high-detail stuff, I started hunting it — precisely because it's a faff for everyone else, which is exactly why it's under-supplied and under-priced.

Same shelves, same budget, better margins — not because I'm cleverer, but because I stopped letting 'annoying to describe' decide what I'd sell.
