You can usually get a web cancel option by changing your address, because some states, including California[1], have laws requiring it be as easy to cancel as it was to sign up.

WSJ offered me an online cancel option after I moved (cough) to California.

It was a digital subscription by the way - usually they have your address on file anyway because you used it to verify your credit card.
