When I worked yesterday at Target, I saw that the Just Dance 3 wii bundle (regular price of $129.99, so the wii has already been this price for months technically) had a temporary price cut to that $99 mark. It is a target exclusive bundle though, so you probably can't price match it, but yea, these signs were out at least all day Sunday, and not a single person asked about it.
So if you want one for 99, I'd give target a call. And while yes, there is the classic 'no call about deals' rule, I'm pretty sure most target will have like 20 in stock, and they should hold at least to the end of the day.
