The median is the middle asking price of live Buy It Now listings for this exact search, so it reflects what sellers are asking today, not what buyers paid last month. Use the 25th percentile as a realistic quick-sale price and the 75th as a patient-seller price. Anything listed well under the 25th percentile is worth checking for condition, completeness, and seller feedback before you buy.
