Tobacco (Where Legal — 50%+ savings)

For smokers, duty-free tobacco offers the highest savings of any category — frequently 50–60% versus taxed retail prices in high-tax countries like Australia, UK, and Norway — outperforming the next-best category (spirits at 20–40%) by 10–40 percentage points. The legal allowance (typically 200 cigarettes or 50 cigars per person) limits the benefit to regular travellers, but the per-trip savings can exceed $150 when flying from Sydney to London. It justifies building tobacco into international travel planning.
