Hey pretty princess1 you start buying your fuel online and you'll start annoying some other duopolies namely woollies & coles! (not to mention the gov, bypassing the excise tax)
What are your thoughts on delivery? I don't think Qantas will freight hazardous materials, you might have to see if DHL has a spare bulk carrier, that could get pricey, even with your online discount.
But don't forget you'll need to keep your online purchase under $1000 to be GST free.... Thanks for bringing that to our attention Gerry, Duh!
