The badge is a bar, not a vibe.

The four checks

Every listing Stamped surfaces is scored against the same four requirements. All four have to pass. There is no partial credit and no "close enough" tier.

• Return window14+ days
• Seller rating97% or higher
• Condition disclosureRequired
• Platform buyer protectionActive
• Undisclosed condition, or no return policyDisqualified

Return window — 14 days minimum

Fourteen days is roughly the shortest window in which a normal person can receive an item, unbox it, actually use it, and discover that it doesn't work. Anything shorter shifts the risk onto you. Manufacturer-certified refurbished stock frequently carries 90 days or a full warranty; that's better, and it's weighted higher, but 14 is the floor.

Seller rating — 97% or higher

Marketplace feedback percentages are imperfect, but they're the most consistent cross-platform signal available, and the drop-off in buyer complaints above ~97% is sharp. A seller below that line can still appear in results. They just can't hold the stamped spot.

Condition disclosure — required

The listing has to say what condition the item is actually in, in the listing itself. "Used" with no further detail isn't a disclosure. Grade, cosmetic condition, what's included in the box, and whether it's been tested are what separate a real used listing from a gamble.

Platform buyer protection — active

If the item never arrives, or arrives broken, there has to be somebody other than the seller who will make it right. A listing on a platform with active buyer protection has that. A direct transaction arranged off-platform does not, which is why we don't stamp them regardless of price.

What happens when nothing qualifies

Sometimes the cheapest listing for an item fails all four checks and the next cheapest one costs meaningfully more. Stamped doesn't hide that, and it doesn't quietly stamp the expensive one to make the page look tidy. You see both, the badge sits on the one that earned it, and the difference is yours to weigh.

What the badge does not mean

Being direct about the edges of this, because it matters:

• It isn't a warranty from Stamped. We don't sell the item, hold it, inspect it, or ship it. The badge describes the terms the seller and platform are offering — it isn't a promise we can independently enforce.
• It isn't a quality review. It says nothing about whether the product itself is any good, only about whether you have recourse if the specific unit you receive isn't.
• It's a snapshot. Sellers change return policies, ratings move, and listings sell out. Confirm the terms on the seller's page before you pay.

If we get one wrong

If a listing carries the badge and the terms on the seller's page don't match what we showed, we want to know — that's a bug in the thing this whole site is built on. Send it to us with the listing link and we'll correct it.
