What makes you trust a secondhand listing enough to buy?

Two listings for the same used console can leave you with very different levels of confidence. One says excellent condition. The other shows the worn corner, names the included cables and tells you which functions were tested.

That second seller has given you something you can actually evaluate even if their item has more wear.

I m building PUPMKT, an evidence-first resale marketplace, around that distinction: photos of the actual item, identifying details, condition and what s included. We re sharing our launch on Product Hunt today.

PUPMKT - Evidence-first resale for games, cards and collectibles

Hi Product Hunt, I am Stephen, founder of PUPMKT. On most resale sites a listing is a story the seller tells. Here it has to carry evidence: photos of the exact item, its identifiers, its condition, one listing per physical thing. Browsing is open, sellers open today, purchases follow. Built in six months with GPT-6 Astra, Codex and Claude under a signed verification chain, every product decision mine. Tell me where the evidence rules feel like friction and where they feel like trust.
