As I recall, credit cards automatically change the money for you, which is a great convenience for customers outside the U.S. and probably also for you Mudcatters. Maybe you could have a standard 3% surcharge for credit-card orders. Though I guess it's expensive enough for the Australians to order by phone--maybe you could let overseas customers snail-mail their credit-card numbers, or (if they trust it) e-mail their credit-card numbers to you. Or maybe you should stop listening to me and let them speak for themselves.
