So my friend bought me a 60 day card as a gift and I wanna add it to my subscription but I can't and is asking me to upgrade to standard and fork over $15. Is there a way pass this problem or do I really have to pay money just to use this game card? Another question is that I'm on my last day of my subscription, is it possible if I wait until my main subscription to finish up and then try to add the card or will it still not work? I don't want this gift to become useless...
