Paypal has finally come to SCEA which means that it is now possible to transfer funds from Paypal to your US account! Previously we could only directly do this in the EU, for the US, there was a long procedure which involved getting a Paypal card and using it as a credit card.
Sony has finally done something good! Paypal can now be used on the US PSN.
As of yet, it is only possible to transfer funds through the SEN website.
