SEPA direct debit? First time I hear that anyone is using this for subscriptions, aren't you from Germany? :-) SEPA direct debit is also used here (Slovakia) but usually to pay for internet/phone/electricity/ and other bills, you basically give them a mandate to draw up to a certain amount and you can revoke it anytime. Debit (or less common credit) cards are I think pretty common for subscriptions but I haven't heard about any shady tactics of preventing you from unsubscribing, I guess that's because all of that is regulated. And in worst case I guess I could call my bank.
