Korean consumer code is 'Best service, Best quality, Best Price'. This seems to be impossible to accomplish since low price and product differentiation is on end-to-end.
However, through thorough understanding of Korean culture and consumer habits, businesses could succeed. Tesco of Britain, recently entered Korea which goes by the name 'Home-Plus'. They are offering everything local businesses are engaging in. And is covering more than 5 % of market share. If Wal-Mart, with their assets and their resources, could have done much better. Personally considering the fact the similar Costco-Wholesales is doing just fine by having huge stores in the city, if their store placement was a little better, they could have had a much happier ending. Wal-Mart just couldn't break the 'wals' down.
