Scifi or Syfy as they now identify themselves as has a free trial offer. I have revived a lot of free magazines though this type of offer. When the bill comes, cancel just needs to be marked on the bill. Don't worry, if its not, they will send another that can be marked as canceled then. The countries the free trial is offered to doesn't appear have any limitations.
