About EauIndex

Fragrance prices are hard to compare. The same scent is sold in five sizes, labeled in fluid ounces at one store and milliliters at another, as a tester here and a gift set there, and marked down on a schedule nobody publishes. Ask an assistant where a bottle is cheapest and you often get a European price, a grey-market listing, or two different sizes compared as if they were the same bottle.

EauIndex is a daily price index for the US market. One page per fragrance and concentration, with every size, the lowest in-stock price at US retailers, the price per ml, the price history, and a plain verdict on whether now is a good time to buy.

What we do differently

• US retailers only, in US dollars. Every price names its retailer and the date we saw it.
• Prices come from retailers' official affiliate product feeds and APIs, never from scraping.
• Sizes are normalized to the ml printed on the box. Testers, unboxed bottles and gift sets are shown separately and never set the headline price.
• Each retailer is labeled as an authorized seller or a discounter.
• Dupes are listed only when the dupe brand itself says what inspired a scent, quoted with a link.
