What is the cheapest way to convert currency, like my USD into KRW?

I know they can charge a hefty fee at the airport for converting currency. What can I do to avoid a fee and get a free exchange?|||I would use a debit card to withdraw money in South Korea as long as your bank is not going to charge high fees per transaction. Alternatively, look at purchasing with a credit card - again check fees first. Otherwise change a small amount at the airport and check out a few banks when you hit town. Hotels will change, but often at unfavourable rates.|||The seller's rates for USD are different (and lesser) from buying rates. i don't have much idea about all this but basically you can never get a free exchange. Airports always charge a hefty fee. They rob people. A bank in the city downtown (in Seoul?) would be a better place to get exchange. At the airport get only what you need for a day or till you visit the bank. Do call a bank before hand. :-P


Good luck.
