Open data
The measurements behind this site, as JSON. Each dataset is the same stored computation a public page renders, refreshed hourly, so the numbers here can never disagree with the site. Free to use with attribution (CC BY 4.0).
Fragrance price per millilitre by concentration
Median price per ml for eau de cologne, eau de toilette, eau de parfum, parfum and extrait across every full bottle we price, by bottle size, with interquartile ranges and sample sizes; plus the measured per-ml premium of the higher concentration on the same scent at the same size.

Strikethrough ("was" price) audit
Every live listing's advertised "was" price checked two ways: against what every other tracked seller currently asks for the identical bottle, and against the highest price that seller was ever recorded asking for the listing. Per store and in total, with the sample behind every share. Nightly.

Fragrance brand discount index
Average and median verified full-bottle markdown per fragrance house (samples, decants, testers and gift sets never set a figure), over fragrances sold by two or more tracked sellers, with a niche vs. designer split. A house needs 10+ such fragrances to be ranked; smaller houses are omitted, not zeroed. Hourly.

Fragrance discounter price index
Each tracked store's median price ratio against the rest of the market, measured over the bottles it shares with at least one other seller. The measurement behind the cheapest-discounters ranking; a store needs 25+ shared bottles and a live deal to appear.

Weekly fragrance price drops
The running week's verified price falls, computed from recorded price history. Every row carries the number of tracked days its claim rests on; falls implying more than 4x are rejected as data faults. Frozen, citable weekly permalinks live under /drops.
