Geez guys, lighten up, everyone has their own game buying preferences, this is CAG, remember? I rarely buy dlc and almost always prefer to wait on the GOTY editions, that's just my preference. I have plenty of other games I can play in the meantime so I don't mind the wait on the GOTY. And yes, you can get much better deals most of the time if you wait.
As for the 50% off expectation? I don't see where that was unreasonable, pretty much all of the other daily deals during this sale were a minimum of 50% off.
I just love it when people get mad when I won't spend my money on one of their favorite games.
