Yeah I've seen the publishers sales once in a while. I can just never afford a whole publisher catalog. Not right now anyway. I've been going for some of the $5 games here and there. Got LA Noire a couple weeks ago including all DLC's for a little over $7 and got Mass Effect 2 over at GameStop.com for $5 at 75% off.
You don't have to buy the whole catalog, they have the individual games on sale as well.
