Oh for sure, but there's a lot of crap to wade through, lol.
It does not in Community side I think although I could be wrong, there is a Ghosts mp discussion thread but it's not active as people have moved on to other games, don't like the game, or don't play CoD anymore, etc.
And doesn't Sony usually give you the bonus if you're a cent off? I've heard of them doing this in the past with pay $50, get $10 back deals in which people buy the $49.99 PS+ 12 month sub and they will credit the $10 to your account.
EDIT: Here it is from a promotion from last year, it never hurts to ask on the PS Blog though just in case.
