- 49 eBay sales of the Olaplex No. 4P from Jan 8, 2026 to Oct 17, 2026, each one checked to be this model (at least half name it in the listing; the rest match it closely).
- eBay prices are completed sales (what buyers paid), not asking prices, from our sold-data provider. We keep only sales of the same product: parts, accessories, bundles and look-alikes are dropped before anything is counted.
- Local auction prices are winning bids on single-item lots at the Kansas and Missouri online auctions we track (HiBid and Equip-Bid sellers), read by our own lot reader. Lots of several units are left out.
- The money math uses our standard costs: 18% buyer's premium, 9% sales tax, a $2.00 lot fee, eBay's 13.6% + $0.40 fee, shipping at cost (never counted as profit) and a 15% buffer for returns and duds. Members set their own.
