www.artisanparfumeur.com, but the Covent Garden store has a few extra items in the sale and some products that have already sold out online, like the 50ml The Pour Un Ete.
I bought 100ml of Navegar, a marine salty (but not ozone-aquatic) woody/spicy fragrance, and Fou D'Absinthe shower gel. If you are in London, it is worth making a detour. (Drivel Kate - if you're in London you need to have a sniff of Navegar).
Navegar is quite light and wears close to the skin, but I prefer that in a fragrance. I have been debating between Miller Harris Fleurs de Sel and Heeley Sel Marin, and Navegar has stepped in and settled the argument at half the price of either. If you have tried and liked the Haus of Gloi Picaroon scent you would probably like Navegar.
Navegar was £46 for 100ml, and the shower gel was £16 for 200ml (both in the sale).
