Would you be willing to answer a few brief questions about PlayStation Forums?
Thanks Guys, just to be sure though, even if i buy it with pre paid psn money as opposed to using a direct pre paid psn plus card?
Yes, no matter how you do it the trial is the only thing that requires a credit card.
I just bought a pre paid ps+ card and just entered the code so even with the ps+ card. you'd be good to go.
