I am fast becoming a devoted follower of the IBAN transaction method. Seems much safer to send the money via bank transfer than to use credit card details that can be scammed.
I wonder what definition of "safer" you are using when you think:
1. pay by bank transfer, money is irrevocably gone, and if actual fraud rather than rubbish service is happening, is transferred between several accounts and becomes untraceable and you have no comeback in either case.
is safer than
2. pay by credit card. If its a scam, you get your money back.
