Can I Get Cheaper Insurance If I Get Two or More Types with the Same Company?

I am trying to figure out whether or not I might be able to save some money on insurance by combining my home owners insurance and my car insurance and getting them from the same company. I was told that this might be able to save me some money, so I am looking into it. I want to get the cheapest insurance that I can that has the amount of coverage that I am looking for. Does anyone know whether I can do this on one of the websites where you can get multiple quotes, or do I need to check with each company individually?
