We record every unit's price at every retailer once a day. A unit earns a place here only when its current, in-stock price is the lowest in our available history from the last 120 days for that seller, and it has genuinely trended down (confirmed over several days of tracking, not a single overnight change) by at least 5% and $20 off an earlier price we recorded, never a manufacturer list price. The moment the price rises or the unit goes out of stock, it drops off this list.
