E-mart, where I usually buy food and things.
E-mart is no.1 discount store in Korea.
(Is the word right? Do they call it 'discount store'? store like Walmart, Carrefour, etc.)
Worldwide no.1, Walmart used to be no.5, but now they withdrawed from Korea.
Carrefour followed Walmart. They also gave up Korean market.
It is said that the two big stores failed localization.
