UK. Did you know that the respected John Lewis provide a pet insurance service. Which? the consumer magazine rated their dog insurance No.1.
The point is this. They are known for their motto, "Never knowingly undersold". They provide a good shopping experience and their employees are shareholders, an innovative concept in Britain. They are probably the best shop for consumer products in the UK. They might do the same for insurance.
They don't provide a coupon or a discount but what you might find is that they provide cheaper insurance in the long run. So I'd check them out.
Go Compare the comparison site compare them against other providers. But beware of Go Compare! They probably receive commissions so are they neutral?
