Perfume/cologne prices

Looking to purchase some fragrances, but I'm wondering about prices compared to home. For example, a 4.2 oz Ralph Lauren Polo Black eau de toilette is $80 here. Anyone have any input on cost and the best place to buy? Just trying to get an idea before we get there. Thanks.

I always found them a little cheaper duty free and no sales tax. Just find a couple you like and price here and if you find a bargain get it. We always liked going to the ships shop and trying different samples each night and then bought the ones we liked the most at the end of the cruise.

Thanks, Lonedaddy. Good advice.

Just visited St. Thomas during Thanksgiving week. I bought a 3.4 oz bottle Chanel Bleu De Chanel Eau De Parfum Pour Homme Spray for $89/no tax at one of the vendors in the Havensight dock. At home, Macy's sells it for $110 + tax.
