The key is to go early on Sundays. Check the weekly ads that Speedy posts in the Game Deals forum - if CC or BB or TRU or Target are going to have Wii's on Sunday, get there early (8 or 9am) and you should be good to go. The last 3 weekends, friends have gotten Wiis at various CC and TRU stores in the South Bay and Peninsula (Sunnyvale, East Palo Alto and Redwood City)
