Best Buy may be hoarding their Wii supplies for one last holiday push. According to reader MidnightScott, his local Best Buy is holding onto their Wiis until December 14th. This same situation happened last year…Best Buy had a final push for holiday sales shortly before Christmas hit. This time, we also hear that Best Buy is holding games as well, such as Mario Kart Wii. It looks like Nintendo is getting a great attach rate of Wii to Mario Kart sales!
