I saw the Ad pop up while looking at my facebook. I am not sure if it's price error, but you can buy Razer phone 2 directly at Razer Shop for just AU$462.00.

You can save an extra $15 off with their newsletter code.

Update-

Thanks to @yeviisxc

It looks like you can reduce the price furthermore if you have Edu access by applying the Edu discount code. The final price will be dropped to AU$392.70
