As I've often recounted, Zellers had several GameCubes available on launch day, which is where I got mine without a preorder. There wasn't even a line. It's like, people don't even consider Zellers as a place for video games, so I'd say that if they get Wiis on launch day (and I don't see why not), it would certainly be a place to consider.
There's a shopping area in Edmonton called South Park, and there's a Zellers, Future Shop, and Toys R Us all within close proximity of each other. That's probably where I'm going to hit.
For whatever reason I've never had bundles forced upon me anywhere for any launch, so I'm not fearing that at all. Should I?
