Just saw this today at JB Artarmon. It's $3 better than HN deal http://www.ozbargain.com.au/node/22866.
jiakz posted in that deal "Just bought the 46 for $1280 with 5 year warranty delivered with 500 days interest free at HN Preston"
Maybe can try to get a better deal or same deal.
Good luck haha, waiting for my blu-ray offer, it got validated this week. i've calibrated the tv and it looks superb
