Target have been slowly getting out of the video game business for months now, since the start of the year really.
Management have been throwing shit at the wall to see if a market will stick but gamers are either very fickle (will buy cheapest anywhere and will research) or lazy/bogged (buy everything at specialist outlet, which is only EB now), no in between. Target learning that the hard way as JB once did.
Kmart pulled the band aid quick, Target tried to make something of the market but hasn't worked out. I expect most of those prices are cost price or lower.
And yeah other stuff is on special too, waiting for official documents to come out though. Other retailers might have some items on sale next weekend too
