Define a comparable basket before calculating
An average price becomes useful only with a dated and consistent selection. Mixing miniatures, eaux de parfum and collectible bottles produces an unhelpful number. Choose a volume, concentration and sales channel, then record prices for the references that actually correspond to your intended purchase and fragrance preferences.
Read the variation behind a central figure
Even within a coherent basket, differences can reflect house positioning and presentation. Compare the total amount you would spend, then price by volume when that helps your decision. This page provides a method; it does not claim a market average calculated without a complete and clearly defined set of observations.
