I just picked Polarium up at Target the other day. They had it on clearance (presumably to make room in their cases for other games). I'm not certain if Target will have the same deal at other locations but it certainly is worth checking out if you've been interested in picking up this Puzzle game.
My wife really like puzzle games, so I picked it up for her and havnt opened it yet. But I know quite a few of you here already have it.
Anywho, just thought i'd mention that!
