Well, I spent a couple minutes trying to figure out how to check PSN mail on the Vita and wasn't really getting anywhere, so popped on the PS3, went over to what looked like a mailbox (I've never used this thing) and what do you know, $10.
Apparently my kid cousins have sent several Call of Duty game invites over the years, and I have a friend request from some dude that reads "i met you threw Journey"
For the benefit of others: Been dabbling in PSN+ with month by month subscriptions since October, have five days left. Usually spend like $30 a year on PSN stuff, got my PS3 in 2009, most recent purchase was Unfinished Swan and Nights a couple weeks ago on sale.
Anyways, nice job buying me off Sony, much appreciated! Nintendo, step your game up!
