I saw my annual premium went up nearly $500 dollars.  I have had Nationwide insurance auto and home since like 1996.     I guess they are recouping the refunds they provided during Covid lock downs.      Mine is several hundred higher than NC state allows them to charge for the coverage I have currently.   In the past it might have been like $100 more, but never several hundred more.  Your options is to pay the overage or find new insurance.   No recent claims, so I am clear to shop around!
