Some people would be very careful with their money and shop around attentively before they part with it. They know that once the money leaves their wallet it is never coming back. And some other people would just buy things without paying much attention to possibility of finding the same product from another shop at a cheaper price.
It is same for car insurance. While many people would confirm that they found cheap auto insurance pretty easily and saved some money many people would still let their policy automatically renew without bothering to check for better deals. Nearly two third of people would never check alternative car insurance providers for quotes at each renewal. This figure is quite worrying in many aspects.
Thinking that insurers know these statistics is worrying on its own. Market economy does not work in favor of consumers if they do not look after their interest. Even allowing the providers to think they can get away with higher rates would work against them. It is essential that consumers push their suppliers to providing better service and lower prices.
One important point is that once you find a more competitive car insurance company this year next year you would probably get cheaper renewal terms as well. So you will keep benefiting from the work you do at this renewal. Putting it off for another year would mean that you would be a year behind in savings. Keep that in mind all the time.
Another point might worry people is the time it would take to look for alternative offers. They should not worry about it at all as it should not take more than half an hour to find all the offers from top insurers in your zip code, get quotes and compare them. At least for the sake of getting informed people should find out what others might offer them.
