merchants – purse.io – shipping to Australia

I am using https://purse.io/shop to buy goods from Amazon (US). As the shipping address is in Australia, shipping will take almost a month.

Does anyone know any tips or tricks to avoid order getting cancelled by earner? Is high or low level earner more likely to cencel order? I don’t mind paying a surcharge for the long shipping time.

Is using a forwarder the only solution? I want to avoid one more middleman if possible.
