🧠 Duty-Free Isn’t Always a Deal

“Duty-free” means the retailer doesn’t charge local taxes — but that 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 anything.

📈 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 Amazon or local retailers
• 🎁 Generic souvenirs — same quality often available outside for 50% less
• 📚 Books & magazines — marked up and outdated
