I just cancelled my NYT subscription, took me 5 minutes. Trying to cancel my Wired subscription, non-US subscriber, means I have to wait for the next delivery to use a number on the envelope to identify myself in order to cancel the subscription. Well, be it I guess.
Wired is the worst. It's literally impossible to cancel online, and they still keep spamming me with "renewal notices" snail mail even after my subscription ended.
