Purchasing perfume at airport duty-free shops is frequently cheaper than buying it at standard domestic high-street retail stores or department outlets because duty-free items are exempt from local import duties, value-added taxes (VAT), and national excise levies. However, savvy shoppers should always compare prices beforehand, as global currency exchange rates, airport retail operating markups, and exclusive manufacturer pricing can occasionally mean that online retailers, seasonal department store sales, or specialized discount cosmetic outlets offer comparable or lower prices.
