If it's travel money, you're probably better off using your credit card
I exchanged money online ages ago as much better rate was had....i used my debit card to pay (using a CC attracts 'cash advance' fees and interest). If i remember correctly I had the money sent to me at work by registered delivery 2 days later. Company called me and asked where i wanted the money sent to as it had to be signed for. Was also an option to collect from one of the foreign exchange places in the airport.
Just check out how legit they are before you send over details.
