How expensive is St Barts? The St Barts paradox is that luxury goods (e.g. Hermès bags, Cartier jewelry, Louis Vuitton suitcases) are tax-free, so about 20% cheaper than in the US or France.

Designer items in St. Barths (Saint Barthélemy) can be cheaper than in the United States, but they are generally not "bargains" in the traditional sense. The primary reason for any savings is that St. Barths is a duty-free port, meaning there is no Import Duty or Value Added Tax (VAT) applied to luxury goods like watches, jewelry, and high-end fashion. When you shop at boutiques for brands like Hermès, Louis Vuitton, or Cartier in Gustavia, the price on the tag is the final price you pay—there is no added sales tax at the register, which can save Americans 6% to 10% depending on their home state. Additionally, because St. Barths is a French overseas collectivity, many European brands are priced in Euros; if the Euro is weak against the Dollar, American tourists can see an additional "currency discount" of 5% to 15%. However, the costs of shipping and the high "island premium" associated with operating a boutique on a remote, exclusive island mean that the base prices are often set slightly higher than in Paris or Milan. You will likely pay less than you would in New York or Beverly Hills, but for the absolute best prices on French and Italian designer goods, continental Europe remains the gold standard.
