You did say mainly, but fairly sure I won't be self importing a washing machine...
That's the interesting part. Why not? If the WM here was $1200 but online with GST and freight was $740, why not? $500 food processor is $269 online, why not?
Now we wont be buying houses, sausage rolls, haircuts online, nor the DIY bits I need tomorrow, but you might be surprised how far online could go. Manufacturers of your WM in China or Belgium or Germany might make it easy. They wont need a shop they just need a website to take orders. If one manufacturer of any type of good did that, the others have to follow.
