I travel abroad with a wide card, which can be swiped in many countries, and the wide card is free of foreign exchange transaction service fees when spending abroad, which is very economical. If you go to Korea to buy skin care products, it is recommended to go to Gloria Duty Free Shop. 63. Silla Aibaoke Duty Free Shop will be more favorable and complete. In these two stores, if you use Guangfa VISA card, there will be discounts or gifts, which can save a lot of money.
