We got ours at Target, check with the guys in the video department and find out what days they get their shipments in out and that will tell you when to check. Our guy said they usually get in 2-4 every 3 weeks or so.
We just happened to be in the target south of us and they had 3. I had to ask too if those were actual Wiis, because I was so suprised to see any there, I thought they must be something else
When you go get one if it is not a bundle, you will want to get at least 1 extra controller, we purchased the WiiPlay game that comes with a controller, the game cost $50 and a controller was $40, so it was like getting a bunch of mini game for $10.
