What the numbers are
Twice a day we pull live US eBay Buy It Now listings for each product, filter out parts, lots, broken units and accessories, and record the cheapest (low), 25th percentile (p25) and median (median) of item + shipping in USD, plus how many clean listings there were (n). These are asking prices, not sold prices (method). History starts in October 2026.
