So I just recently purchased a PS4 and was so excited when I got it that I didnt go through any of the paperwork. After playing Ghosts and finding out that I cant play multiplayer I headed to amazon.com and purchased a year subscription for PS Plus. Basically the next day I found out that with the purcahse of my PS4 i was given a digital code for a subscription. Is there anything I can do? Can I still enter the code now and have 2 years paid for? If not, what are my other options?
