Duty-Free Isn’t Always a Deal

“Duty-free” means the retailer doesn’t charge local taxes. But that still doesn’t mean the item is cheaper than what you’d pay in your home country. Brands often inflate base prices at airports to protect global pricing.

Key hack: Check prices in your home currency using apps like Skyscanner Shopping or PriceSpy before buying.

What’s Actually Worth Buying Duty-Free?

• 💄 Luxury cosmetics (Estée Lauder, Lancôme) — often in travel sets not sold elsewhere
• 🕯️ Perfumes and colognes — especially value bundles (2-for-1 packs)
• 🥃 Premium spirits — whiskey, rum, cognac — can be 15–30% cheaper, especially in UK & Dubai
• 🍫 Local gourmet snacks — such as Swiss chocolate (Zürich), French cheese (Paris)

What to Avoid at Duty-Free

• 💊 Over-the-counter medicines — often overpriced
• 📱 Tech gadgets — prices usually higher than online or local retailers
• 🎁 Generic souvenirs — same quality often available outside for 50% less
• 📚 Books & magazines — marked up and outdated
