Field notes
The seller table separates non-delivery, overcharge, duplicate payments, and wrong goods, and includes a likely range beside each failure rate. It reports that low-sample sellers are greyed out rather than rated, while the displayed main list requires at least 30 paid calls. The page describes a six-hour purchase-and-check cycle; the figures and operating claims are presented by the site, not independently verified here.
