Second chance offers are a legitimate tool, used by sellers who more than one identical item, or for sellers who have a difficult buyer who refuses to pay. ( often with no contact. ) While your little description is rather amusing, it does highlight why there is distrust of the system by buyers. This results in very poor uptake ( around 25% in my experience ) of legitimate offers from genuine sellers.
