Has anyone else been getting checks from their car insurance carrier(s)?

In the past couple of weeks, I have gotten two checks attached to letters saying. "This refund is due to a recent adjustment to your policy." One was from my current insurers for $46 and change, the other arrived today from my previous carrier and is for just short of $207. I just turned 78 and haven't had a ticket since the night my now 53-year-old daughter graduated from high school. I was driving a '72 Chevy Vega the last time I had an accident that was my fault. I did take some sort of flying object in my windshield on the Interstate a few years back. I was rearended at a stoplight in 1997 and because of Florida's no-fault law my insurance paid my medical bills. I settled a claim with the driver who hit me, he had forgotten to take his insulin and was out of it at eight in the morning. My insurance has been going up all the time and I was shocked to get these checks. I posted this in the Seniors forum too, because I think it may be age related.
