> I recently generated a single-use card with a $1 spend limit to sign up for a free trial of Masterclass, for which I would have been automatically charged an annual membership fee of $180 if I’d forgotten to cancel on time.

Now, i understand that most businesses most likely won't bother, but theoretically, in a situation like this: What stops a business from sending you a notice about your agreed payment being late?

Unless i am missing something this isn't really all that sound advice? Why not keep a calendar with reminders?
