Currently selling for $649 at JB Hi-Fi
Seems a good deal. Harvey Norman usually sell them for $588 but have them on sale for $488.
Eligible for $50 cashback from Canon
Is also over $300 so if you have AMEX you can get $100 cashback from them also
If you have multiple AMEX cards (and registered them for the deal, which is still open for registrations), buy in store and put $300 on one card and the balance on the other. To get the AMEX cashback, you don't need to spend $300 in one transaction, so after spending $188 on the second card (you spend $488 in store and get cashback after), you only have to spend another $112 sometime to get another $100 cashback (so is virtually free if spending that amount)
EDIT: The Good Guys sell for $414 (as noted by Calvin101), so if you get Harvey Norman to price match, after cashback it comes down to $264.
I have one amex account, but 2 cards, primary card and secondary card for my wife, wonder if it works?
