Is it cheaper to buy a decant or a full bottle of Diptyque Philosykos?

The full bottle is cheaper per millilitre: $1.75/ml for the cheapest full bottle (100 ml at FragranceNet, $174.99, read Oct 6, 2026, 10:45 UTC), against $3.15/ml for the cheapest decant (8 ml at FragranceNet, $25.19, read Oct 6, 2026, 10:45 UTC), about 1.8 times as much per ml. A decant costs less up front, which makes it the cheaper way to try the scent before committing to a bottle.

Why is Diptyque Philosykos cheaper here than in stores?

The prices come from established discounters sourcing through overstock, closeouts and parallel imports, which is how a bottle can list below the department-store price. We compare retailer data and do not authenticate individual bottles; our authenticity page explains how sellers are vetted and what parallel import means for warranty and packaging.
