The difference is a fee your bank has imposed on the transaction. The global financial crisis, in combination with recent legislation in the US has put significant pressure on the profitability of the banking and credit card industries. As a consequence, many banks have drastically increased the fees associated with international transactions in an attempt to recoup losses in other areas. This dubious business practice is unfortunately completely out of our control. If this happens to you, please let us know and we will do everything we can to help you recoup these fees with the bank.
