Is there a particular reason my American Express credit card isn't accepted on subscribestar? I just got this card because I can't buy the game in Germany (as many people here have already said) and now this. At least I don't have to pay a fee for this card. Will it be acceptable in the future? Is there a mistake on my side? Or is there any other payment option? I really want to play the full version. :(
I have AmEx, they have higher transaction processing fees IIRC (likely how they fund their cashback program), so some places don't accept it, and there may be SS and AmEx policies at play too. Visa, Mastercard, and Discover are accepted according to Subscribe Star (you can see them at the bottom of the website).
