I already opened it, why the hell would I buy it on Sunday, and keep it sealed hoping that a week later there might be a free game with it? So at this point can't I just rebuy tomorrow and return just the console (new one) with my old receipt?
Well, hopefully you at least activated Playstation Plus the day you picked it up.
A big part of the reason I bought mine on Halloween night was that I knew I'd be able to log right in, grab October's games (Resident Evil and Platinum Transformers game), and then have new games to pick up the next day.
Otherwise, yeah... you probably should have waited.
