Jeju island bazaar is located in. Near Silla duty-free shop. Jeju island is one of the few relatively large stores, but compared to domestic supermarkets in Shanghai, for example, or a lot of small, but much cheaper than small supermarkets. Also Xin Ramen is a local specialty. Sometimes I also encounter discounts at the mall. With more than 8000 won, the tax will be refunded. Anyway, if you have a chance, you still have to go first. You got a good deal.
