Confusion when living in the states and buying parts from Australia

Pay by credit card. it is not a supplier you have used before. You don’t have much recourse with sending a wire, if the vendor does not send you the parts. With a credit card, you can get your money back. You will pay a fee of like 10-25 bucks on the CC, a wire depending on the bank is 50-100 bucks. You will also have import duties, most of the time UPS or DHL or the sort will cover the duty and bill you for it.
