Duty-Free Shops are retail outlets that sell goods without charging the local import duties and taxes. These shops are typically found in international airports, seaports, and border crossings, allowing travelers to purchase items at lower prices compared to regular stores. The products available often include alcohol, tobacco, perfumes, cosmetics, and luxury goods. To shop at a Duty-Free Shop, customers must show a valid passport and proof of international travel. There are limits on the quantity of goods that can be purchased and brought into a country without incurring additional taxes. This makes Duty-Free Shops popular among travelers looking for savings on premium products.
