You can use privacy.com as another commenter has written. But one catch is I believe you can be on the hook for subscriptions where your card no longer works but you haven't cancelled your subscription. So they can send you invoices and even send it to collections. Although I strongly feel that at least for transactions of a sufficiently small size (normal retail subscriptions) cancelling your card should be legally considered sufficient enough for voiding your future subscription. I'm open to hearing counter arguments but I think the consumer shouldn't have to jump through even the smallest of hoops setup by vendors in order to indicate that they are no longer interested in future transactions.
