About
Flacon Index is an independent record of what fine fragrance costs on Amazon US, kept day by day. It answers one question: what does this bottle cost today, and who is selling it?
Why it exists
Buying designer fragrance on Amazon is confusing in a way that buying it in a department store is not. The same bottle is often listed several times, by Amazon, by the brand's own storefront and by resellers, at prices that change from one day to the next. Sizes and strengths are priced unevenly, so the bottle that looks cheapest is often not the lowest price per milliliter, and “was” prices are not always what a bottle usually sells for. We built this site to put all of that in one place: every full-size bottle of the fragrances we follow, at its lowest current price, with its price per milliliter, its price history as it builds and the name of the seller.
How a fragrance page is put together
Each fragrance page combines two kinds of information. The prices come from our daily check of Amazon US and are recalculated every time the site is rebuilt. The description, notes, launch year and perfumer come from the house's own published information and major retailers, rewritten in our own words, with how we check them explained on the method page. We keep the two apart on purpose: what a fragrance is does not change daily, but what it costs does.
Editorial principles
- We report; we do not rate. You will not find “best” lists or scores here, only prices, sizes, sellers and how a fragrance is usually described.
- Facts are checked against a named source, and anything we cannot verify is left out rather than guessed.
- Flankers and dupes are kept separate, so a price always belongs to the exact fragrance named.
- Every price has a timestamp, because a price without a date is not much use.
Why Amazon
Amazon carries a wide range of designer fragrance in the US, often from several sellers at once, which makes it the place where prices vary most and a record is most useful. Every price here is an Amazon US price.
Independence and funding
We are not a retailer and we do not sell fragrance. We are not affiliated with any house named on this site, and the houses do not pay to appear or to be placed higher. All brand names and trademarks belong to their owners. When you buy through our links we may earn a commission from Amazon, at no extra cost to you; that commission funds the site and never changes which bottles we list or how we order them. Details are in our affiliate disclosure.
How to use it
Start from the ledger if you want to browse, from a house if you have a favorite brand, or from the sale page if you are watching for a drop. Each fragrance page shows every size and strength side by side; our guides explain strengths, bottle sizes and how to spot a fake. The method page sets out exactly how prices are collected and checked.
