LOL, it costs more than an original version...youtube video shows the poor quality. Why would a person want to buy a poor quality substitute for more money?
When I buy something from the US and want tracked shipping it costs me around $40. If I don't do that and the item does not get to me I have no recourse with the post office or the supplier. As I said, I believe there are restriction on vaping in Australia, so it might be hard to import product. Try to have a Provari shipped to Singapore and see how that goes. You can still buy them there, but prices are way higher than for us.
I don't know what the actual situation in Australia is and I hope someone who does will let us know. In the meantime I do know the situation could be very different there than here
