Got the link in an email. When I went to the site it only had 10% off.
12% discount offer valid to 11:59pm 30 September 2019. The discount is automatically applied when getting a quote. Discount applies to base premium only. Additional options such as specified items cannot be discounted. These options or cover which can be purchased for an additional premium includes extra cover for specified items, increased cover for rental vehicle excess, removing the policy excess and charitable donations made.
Price isn't a gauge of whether insurance is insurance or a good deal. I would pay more if I knew I was getting real insurance, that would pay out if needed. Only historical evidence can show this.
