The Breville The Boss Pro Kinetix Blender has been listed as a "Last Chance" item on the Costco website.
I originally purchased it from Costco when it was $299.99. The blender performs well and has many great reviews. I do find it a bit noisy though.
This looks like the best price on Google by far.
Bought this from David Jones on the last deal for $225. Good machine.
