190,465 daily price readings across 6,609 discounted listings, taken over 44 consecutive days. Of the 4,157 listings tracked for a month or more, 72.3 percent never changed price once, and the listings advertising the deepest discounts were the least likely to move at all.

How we handle our own numbers

Every study here states the days it covers and what its evidence cannot settle. We do not use a short record to claim a lowest-ever price, and we do not call a retailer's sale fake. The method behind the record is written up in full on how we verify deals.
