Buy from Sony for $2795 Delivered. Then stack with the following cashbacks:
Cashrewards: access Sony Australia: 7% cashback = $177
Amex Statement Offer: Pay with your Amex $300 spent another $60 cashback
Sony promotion: $200 cashback, or more depends on your TV size and promotion
Final price for the 55" OLED: $2795 - $177 - $60 - $200 = $2358.
On top of this you may also get a further 10% off of the above price via price match option:
I submitted a price match request with Sony Australia $2515 (2795 - 280) (with The Goodguys sale last night) - essentially, it's 10% off, I believe it will apply for any OLED TV with the cashback promotion: https://store.sony.com.au/television-OLED
You need to create a Sony account first then log in and put in a price match request. A Sony representative will update your cart with the new TV price (Do not remove your item once it reflects the new price).
And the final price I've paid was $2095 after the above cashbacks and promotion
