How this price is computed
The band comes from live eBay comparables and FlipGap's own cross-marketplace listing corpus, trimmed to the interquartile range so bundles, parts-only and sealed-new listings do not distort it. "Typical" is the median of that trimmed set. Bands refresh whenever the product is priced again and pages are only published when the sample is large and consistent enough.
