The description and the price are the SELLER’S, copied from their listing and not checked by us. The badge is OURS and is one unpaid handshake: “answered unpaid” means it answered us once without asking for payment, which is not a standing offer, and an unpriced listing is unpriced rather than free.
Knocking goes to the knock page, which reads the terms live before anything is signed. A listing can be out of date in both directions, which is the reason to knock rather than to read a row.
