I'm relatively new to the playstation community, so please forgive my ignorance here.
Now, I'm aware that Playstation Plus is coming to the Vita in November. Is there any way to purchase a year's worth of Playstation Plus for the Vita whilst counting toward the Big Savings promotion? I figured Playstation Plus was an account based subscription, rather than a system based one, and that I'd be able to purchase it on PSN for my entire account; however, I hear that people purchase a Playstation Plus subscription via the PS3's PSN store, or with physical cards (which apparently do not count toward the promotion?). Any clarification would help--thanks in advance.
Notes: I do not own a PS3.
