I just bought another one on ALI for AU$6.49 inc free shipping plus tax.
I was searching with out being logged in and got the cheap price. When I tried to buy it I needed to log in and found the price jumped to over AU$20.
My simple solution was to spin up a VM (VMWare Virtual Machine) running Win and found the same AU$6.49 for new customers.
I registered a new customer and bought it at that price. It is on its way for delivery next week.
ALI make enough out of me and I am somewhat displeased with their dodgy advertising.
Please let me know if anyoneone else manages to get this deal.
YMMV
