Nowadays, due to covid, consumers are getting used to using delivery services. However, due to the ongoing early morning delivery war, competition is becoming fiercer among delivery companies. Because of this, recently, Lotte, GS, 프레시지 and some companies are withdrawing from early morning delivery services. Yet Coupang and Market Kurly, SSG, NAVER have maintained these services. I think Coupang will be winner eventually! Because Coupang has "creative" monopoly. Also, the company has logistics centers across the country. They're delivering things to their customers in one day. There are a number of the side effects from what they call "Bullet Deliver", though. In conclusion, Coupang has a mounting concern which needs the future alternatives!
