All subscriptions should automatically cancel if you stop paying.
That’s a bit circular though because they just keep billing your credit card.
In Europe, we have debit cards and some banks allow you to create them on the go. I’ve stopped bothering canceling stuff, I just create a new card for each recurrent payment and I cancel it when I don’t want to use the service any longer.
What Service do you use? I’d like to do the same, because it’s not always clear by the charge on my statement who I’m paying. I would imaging having named CCs, like email aliases, would help me keep an eye on things.
That sucks. I’d rather just pay it manually every month, or with a script running on my end.
