Travel Haus offers this service as a convenience to our travelers.  We are doing this as a courtesy and the exchange rates are determined by the company we purchase the currency from.  The company we use is normally very competitive with the rates you get at the airport currency exchange offices.  You may purchase currency on your own if you choose to or find a better rate.  Credit cards and ATM's usually offer better exchange rates than if you purchase currency but you need to make sure you are not charged any international transaction fees by your credit card company or bank.
          The rates shown on TV, Online or in Print are wholesale exchange rates used when banks electronically transfer $1,000,000 or more to another overseas bank.  These rates are not intended for retail purchases when buying cash in the United States or overseas.  Currency Exchange is no different from the retail market where there is wholesale and retail pricing.
