Apparently, if you're willing to trade in 2 qualifying Wii games, you can get SSBB for $9.99:
I called my local store and asked what a qualifying game was. They said, basically anything that's a "regular price" game and that isn't sports. That doesn't really help me. There are a lot of Wii games that come out at less than $50, unlike some other console games...
Anyway, anyone seen a list of qualifying games?
