I stack my PS+ with another year here and there. Right now I'm through September 2014 and haven't bought one since before PS4 unveil. Getting one for less or with bonus months is my favorite way to go.
I was talking to brink. He said he buys 3 month at a time. That adds up to 71 and some change for a year. I buy a year a a time. And now is a good time to do it cause the deal on the psn. If you get a year you get a $10 credit. I did a year last week and I'm gonna do another this week so that will be 2 years for $80
I would buy one but i'm broke till next friday so i'll miss out on this oh well
