I am trying to buy DS some shoes from 6pm.com in the US. I'm not sure what about how to use an Australian credit card on their site. I have entered my US HopShopGo (1st time user) address for the shipping address but it also wants a billing address which they say must be the same as the address on my credit card, but, it only has US states and nowhere to change the country to Australia. I have sent them an email asking what to do but as it's still NY's Day over there I'm not expecting a fast response. I was hoping someone that shops a lot from the US might know what to do. Maybe @Elijahs Mum.
