The multi-policy discount can add up to a premium saving of five to twenty-five percent per policy, depending on the particular insurance company. It is a valid inducement for you, the insurance buyer, to purchase all of your policies from a single insurance company. To not avail yourself of this great cost cutting opportunity would be a big mistake. Purchasing all your coverage in a single company has the added advantage of eliminating possible coverage gaps through the counsel of a single insurance advisor. Similarly, insuring all your vehicles in a single policy, can yield additional premium discounts of ten to fifteen percent per vehicle.
