Just got a great deal on a home and contents policy that was coming up for renewal, already had my car insured with AAMI. If you're an existing customer you get the 20% off on another eligible policy, new customers would have to buy a policy and then get a link to allow them to purchase a second policy for 20% off.
Runs until the 5th of July.
There's a table of eligible policy combinations on the T&C page. Worth noting that there's a range of policies including greenslip and landlord listed there also.
It’ll still cost more than going elsewhere
