That is a great question! The answer really depends upon your insurance companies, and their discount rates. Shop both yours and your spouses, and ask. Also, if there are multiple policies already with one carrier, it might make for a deeper discount with them. Since I don’t know who your policies are with, I’m sorry but I can not give you a dollar or percentage amount specifically. Best answer, call them and see! Congratulations, I pray many years of happiness and blessings for you!!! Thanks for asking!
