Heh heh! Just happened to stop by a Target store other than the one I usually shop at to buy a few things, and just decided to zip by the Xbox games and see if they had any clearance copies of Left 4 Dead. On the shelf behind the glass was the Game of the Year Edition marked $59.99. I glanced down the side of it to check out the labels, and noticed one of the labels was in a different position than the rest, indicating that it was not the GOTY edition. So, I have now purchased yet another copy of Left 4 Dead for $12.48.
So, if any of you want this game on the cheap, I highly recommend checking your Targets. Obviously it is not too late, since I just got that copy today. The Target I found this one at is a pretty busy Target too. Other people on the internet have found copies of the regular edition hidden behind the GOTY edition, sounds like this is pretty common. It honestly makes no sense the regular edition should be clearanced so cheap when then GOTY edition's only difference is content that is downloadable for free. This is really a steal.
