I had United Health once. They were horrible.
I too was a “member” of AARP, only to get discounts on lodging, I traveled a lot on business.
I subscribed on one of their “deals” for 2 years.
When it expired I still had the card and the motels and hotels would just see the card and give me the deal. Smile.
Later, the motel/hotel chains that I normally stayed with had their own good deals for business travelers an it no longer was important.
But Yes, I hated Leftist AARP from the beginning.
