Normally changing home insurance nbn health cover etc…. I do it without blinking and harvest discounts/points.
I have been with AAMI insurance for 8 years now for my car because they always come out cheaper.
This year my renewal came in around $200 more than when compared with other companies.
My only issue is that I am a “diamond member” which apparently is hard to get and entitles you to a discount.
My fear in switching is that next year my new policy will naturally go up and I won’t be a diamond member.
So is it worth the $200 to be diamond?

so you are paying $200 per year extra to be a diamond member which entitles you to a "discount"?
