I can't speak for France, but I bought a 1.7 oz. bottle of Laila in Norway (also available in DTD) and it was selling for $57....the same as the retail price online at Nordstrom and other brick and mortar stores. I'd think France would be the same as stores
Whereas the bottles of wine/champaign in France pavilion and elsewhere are considerably more expensive than local; I have found perfumes are right in line with department store counter pricing. When Chanel Chance first came out, I wanted to buy it right there in France; but thought I'd save money waiting until I got back home. I was shocked to see my Chanel counter was actually more expensive than the Epcot France perfumery.
