I missed out on the 12-months-for-the-price-of-12 deal last month, and just before the 12-month subscription went up to $79.95, too. :-(
However, I noticed that Target and Woolies near me (Innaloo, WA) have various membership cards (on the stand where they also sell iTunes and other gift cards), all still at the old price. Out of curiosity, and a desire to save $10, I bought one and tried it out. To my surprise, it worked! Expecting the card to give me $69.95 credit, it instead gave me a full 12 months extension on my PlayStation Plus account, valued at $79.95.
Win! :-)
I haven't checked anywhere else, but I'd expect that these cards may still be available all over the place. Anyone care to confirm?
Not really a deal, just stores selling slowly their old stock.
Still worth grabbing if you want, I remember buying a 20 buck 3 month card way back when the first big price rise came, that's about it.
