I must admit I was very skeptical about all this !!! And above all - There we go, they want the Credit Card details !!! I don't even know the current exchange rate but proceeded thinking nothing will come of this .... Within minutes I was sent the RESET CODE along with the RECEIPT FOR PAYMENT ! It worked like a charm ! The FIRST , but definitely not the LAST time I will be using this site ! Thank you ! Anthony Campbell Printamedic (South Africa) Cell: 073 580 8517
