I subscribed to the Popular Mechanics and wished to cancel my one year subscription so I could subscribe to Wired instead. I wanted to cancel it but I can't see any option in the iTunes. Should I contact the Popular Mechanics? or is it Apple that I should contact? If you're asking why I want to cancel, it's because Popular Mechanics seems to be degrading in quality and I don't get any response on my questions. Their magazine is basically crap on the iPad because it lacks the Wired magazine's design.
