When a product shows Amazon's "bought in past month" label, ASIN Lens uses that real figure to bound the estimate and to calibrate the curve for its category, so estimates get more accurate the more you browse. Estimates are meant for comparing products and sizing markets, not as accounting data. PRIVACY No account, no tracking, no analytics. Settings, cache and history stay in your browser.
