Liquor (Spirits — Massive Savings)

Spirits are the best duty-free category with consistent savings of 20–40% versus high-street prices, outperforming the second-best category (premium fragrances) by at least 5 percentage points on average. Scotch whisky at UK airports, cognac at Paris CDG, and tequila at Mexican airports offer their home-country product at the lowest prices you will find anywhere—typically 30% cheaper than typical rival retailers abroad. The Changi Airport liquor selection is widely considered the world's best.
