@chocolatkey hell, I would never give google my payment details. I only use Google Play Card's ;)
Also, I like to support my hobbies directly if I can, for exactly that reason, why should I give Google money that is for another company when I can ensure it.
It's the same with PayPal. Stripe probably has the lowest fees, so I pay via credit card directly. I just wrote that sentence for people that would like to support you but have no other way to do it than that. :)
