While web is so clugged from errors and scammers of any kind, I suggest bank transfer royaties payments.
Actually therea are only 2 options available for Creators/Designers:
Paypal (I never had problem with that, I use it since decades, it’s the excellence for online payments, but recently I noticed something anomalous on it too…)
Check
(Too hold method. Have I to wait a paper check by post from U.S.A. ?)
I like Paypal very much, it works very well for everything about payments of any kind. Actually, sometimes web is clugged. I will of course mantain my paypal, but I noticed other online business opted for bank transfer option too, it can be another choice for whom preferring it, and to complete the choices available for everyone.
