Cashback in the form of Visa Realcash cards, from $125 up to $300.
I was in the market for an aircon, so saved myself $125 on a $799 LG: http://www.thegoodguys.com.au/buyonline/LG_Electronics_C2.5k…
Delivery was just $2.
Have an older LG model at home, which I have been happy with. 5 year warranty on them.
Note that some Samsung models have cashback from Samsung themselves, which you can stack.
check that the 1500 limit has not yet been reached before buying: http://www.thegoodguys.com.au/buyonline/BonusOfferListView
For online orders you do not get a docket number, which you need to claim. Phone 1300 466 348, and they will give you a docket number if you get them the web order number.
Even with their cash back, some models are still cheaper elsewhere. FWIW, Samsung have their own cash back promotion running atm. I just received a Samsung 7kW split system from Appliance Central for $1630, and Samsung provide $200 cash back on that. Here's the one I ordered: http://appliancecentral.com.au/shop/index.php?route=product/…
