With the release of the 1080 Ti, the MSRP of the 1080 GTX has lowered by ~$100 USD and Amazon US has reflected this price update.
I imagine local retailers will follow this more aggressively in the coming weeks, but still this is cheaper than any listing on staticice.
There are other brands and models available for comparable pricing (including harder to get models in Aus).
Still prefer local @$699
