Wow I really thank you for warning me to buy it only from amazon.de, otherwise my cousin would have buy it from UK and it might not work for me being in Germany.
I will order one code for PS Plus from amazon and the games I could pay them via PayPal?
It's really strange to input my personal data from a ID just to confirm age, I still think it's just for the 14 days trial but anyway, I hope it will work like this :) Thank you very much again!
