do i have to preorder a wii or can i just go pick one up?

well. i'm getting a wii and i just wanted to know if I could pick one up anytime or if i have to preorder one.  If I have to preorder one, how long should i do it in advance too?

Walmart and Sam's club have wii bundles as well. They sell out eventually a week or two after being listed but since a lot of people just look for the console they tend to not search for the bundles.  

walmart seems to be making each and every online wii a bundle. Seems that is the only way to get them online except when an online website offers a few thousand online once in a blue moon. They sell out within minutes then.

Which is why you cannot get one for retail on Amazon.
