I wanted to order filters just once before committing to an auto reorder on filters for a water fountain purchase for my cat.  Could not place the order unless I committed to the reorder program.  If the cat doesn't like it, I will forget to cancel and pet safe will continue to ship, which of course is what they want.  Either that, or I will have thrown the paper work away and forget where I ordered them from and they will keep shipping and billing.  Forget it pet safe.  Your fountain is going into the trash tonight and I will buy a different brand!
