@waxwing @pete canceling a CC payment doesn't cancel your obligation to pay per any agreement you made. Sure, few companies are going to sue you to force you to continue some $10/year subscription, or whatever, but you're always talking a risk that they won't send your bill to a collection agency that will harass you.
@pete can't a person just automatically, *easily* cancel the payment on the credit card (or whatever) side? Then simply the fact that i've sent an email saying 'cancel' should mean they'd be pissing in the wind if they tried to enforce payment on something i didn't want.
if the answer to the first question is 'no', then that's very interesting.
