Some do and some don't. When I sign up for them and they are auto renew, I mark my calendar, then edit my payment info so it's my choice. This site doesn't allow one to get into their account to edit their payment options, nor was I able to find anywhere that it states it's auto-renew. I was told it only says that when you sign up. Sites that are on the up and up put that info out where it can be found at any time. I can't believe I missed though it as I'm VERY aware of this and read that info pretty carefully.
