Since you mentioned ALL the carriers, the best way to do it is through CSG.How do agents go about getting all the carriers Medicare Supplement prices for the plans each year to determine the cheapest one?
There are two ways to get CSG. Buy it or get it free from your FMO. Last time I counted, I had 12 different FMO accounts. Most I didn't ask for.
The only FMO that lists all of the carriers is Agent Pipeline. They even list carriers that they don't represent.
That's the easiest way to get all of them.
