Changing moneny at a good bargain

I changed some Korean won to US dollars today. To change money at a good bargain:

1. Use Korea Exchange Bank (외환은행)
2. Use internet to get 55% discount for commission

I used Kookmin Bank because there is no KEB nearby. Compare when changing $1,000 at 6th April.

1. KEB: To buy $1, you should pay 948.20 won. After applying 55% discount, 939.24 won for $1. So you pay 939,245 won for $1,000.
2. IBK(기업은행): To buy $1, it costs 951.35 won. After applying 30% discount, 945.75 won for 1$. So you pay 945,755 won for $1,000.
3. Kookmin Bank: You can get 50% discount when using internet. Exchanging rate is 2ndly low, follows KEB.
   

(환전. 은행 마다 환율이 다르다. 외환은행의 환율이 가장 좋고 인터넷을 이용하면 55%의 수수료 인하를 받을 수 있다. 공항에서 환전하지 말것. 환율이 안좋은 은행과 외환은행을 비교할 때 $2,000 정도 환전하면 1만원 넘는 정도의 차이가 난다.)
