If you're going on a shopping spree or staying in a hotel in South Korea (especially Seoul, Busan and Jeju), I suggest you read this guide on the proper procedure and some tips on getting your tax refund from the time you enter a store/hotel up to your departure at the airport ;) The VAT (value added tax) and luxury tax can be as high as 10% minus fees (~8%) so if all your purchases add up, you might just get some cash back for your next trip or use it to buy some food while waiting for your flight =)
