I'm not sure if this qualifies for a deal, but my last hack? was pretty popular after someone else posted it as a deal.
Coles car insurance will basically let you pick your price as long as you don't get too greedy.
I recently changed over and saved $400 on my annual premiums.
steps:
start quote
when you come to the question: Who is you current or recent insurer? select: I don't know
fill out the rest
when you come to the end with the quotes, down the bottom it will say: apply for price beat guarantee. click it
this is where the fun starts, type in the price that you deem worthy and see if it accepts, I tried 3 times and it accepted all 3 times and I finally settled on the last one as it was a pretty good deal and I wanted to lock it in.
Flybuys card holders look to benefit greatly as well.
Mod: Proceed at your own risk, as per terms of service: "The price beat guarantee in the relevant Offer will not apply where WIL determines that there is insufficient evidence of the proposed renewal premium amount or, if applicable, the existing premium paid or payable. Without limiting this, WIL may require you to provide your renewal notice with your current insurer and/or your current insurance policy as evidence of the amount of premium paid or payable. If WIL requests that you provide proof of insurance then you must do so before the end of 7 days of the request."
