Not as good as the Optus deal a few weeks back @ BigW but this seems like the best price for Aus stock at the moment. Free delivery (within a day or two), which means you will get it before Xmas.
It is a clearance line so might run dry soon
BigW have it on at $499 from today but checking 3 stores yesterday, they all had zero stock
Edit: it appears it has come on at 449 in a few spots now e.g.

$399 at Harvey Norman, which goes down to $300 with the $100 Amex offer.
