Be aware of when your credit card expires and is renewed. It used to be that automatic debits flowed smoothly from one card term to another, until a few years ago when my earthquake insurance company arbitrarily changed their rules. They cancelled me for not advising them of the automatic renewal, which as I said, was a seamless occurance in years prior. I think they did it on purpose, to be able to get rid of their older, best, most comprehensive policies that they no long wrote. Underhanded BS. So I had to pay more for lesser coverage by far. I wish I'd taken it to the insurance commission. Stinkers. Now, whether it's needed or not, I let everyone know that my card's been renewed, even tho it's not necessary to do so for most.
Another stinker: the California DMV. If you move and put in a change of address, it doesn't matter to the DMV. They will not allow mail to be forwarded. When I moved out for the earthquake rebuild, they sent my registration renewal to my demolished house, and did not allow the Post Office to forward it to my new address. That cost me almost $500. And how was I to know that DMV doesn't allow the Post Office to forward their notices. Who knows that? Perhaps Florida is different, but just thought I'd mention it in case.
