Precautions for shopping in duty-free shops:
1, about the price
Duty-free shops are definitely cheaper than domestic counters, almost 5-9 fold, and most of them are 7-8 fold. Among them, suits are the most cost-effective, and can be discounted below 50%. Most of the best-selling things are newer than the counters.
2. About gifts
Duty-free shops also offer gifts, similar to domestic counters. When you buy enough, you should give a certain number of gifts. Sometimes you should buy a product before giving gifts.
3. About Pakistan
Duty-free shop is a "tracking" service for you from the end to the payment, and BA is also a cashier.
Actually, the bus is still divided into counters. Be sure to ask which counter it belongs to. Pakistan accepts commission. So, if you want to have a good talk, you can send more gifts.
4. About the limit
For example, the Christmas limit of some makeup is available in duty-free shops, and duty-free shops have unique limits, including makeup and skin care. For example, EL's face cream has a limit of 75ml, 100ml, and there are several packages of make-up discounts, as well as make-up plates. Basically, a box can handle makeup, which is super practical and super economical. Some big brands of bags also have special donations from duty-free shops.
5. Shopping instructions
Passengers entering and leaving the airport need to show their boarding passes and passports (that is, they need passports and registration cards to buy duty-free goods in duty-free shops). If you transfer abroad, please explain it to the sales staff (because some countries and regions restrict transfer passengers from carrying liquids and colloidal items).
Duty-free goods are also sold on the plane. Generally, after the plane is leveled, the stewardess will show all the product manuals, and you can also swipe your card.
6. About payment
All goods in duty-free shops are priced in RMB, and can be paid in cash in RMB, US dollars, Hong Kong dollars, euros and Japanese yen, or by various credit cards. Domestic cards are unionpay, and there is no handling fee.
