This is quite possible and the reason why is because some of our banks do not charge in US dollars but rather in other currencies such as the Euro. Because the currency exchange rates fluctuate daily, the amount charged will not exactly equal what it shows on your invoice. In fact, in many cases it will show less as each day we undervalue the exchange rate to give you a slight discount before charging you. Of course, some banks also like to take their commission for these multi-currency transactions and if your bank is like this they may charge you extra fees as well. Unfortunately we can't do anything to avoid this but if for some reason your credit card shows that you were charged much more than the amount you paid please contact us
and send in a copy of the statement (fax or email) and will we do our best to rectify the matter by applying an account credit.
