I like to look for a deal but if the service is sacrificed in making a deal then I will usually turn it down. I like a quality over quantity approach. So with that being said, most of the time when I see that I can save money if I bunch all of my services together I weigh that against the cost of losing quality of the service.
That is how I am with my car insurance Ontario. I am not quite sure that I want to put together all of my insurance services in to one umbrella policy that covers everything.
