MotionPlus for Wii

Amazon.com offers the MotionPlus for Nintendo Wii for $15.26 with $4.98 for shipping. (Spend over $25 for free shipping.) That's $2 under Saturday's mention and the lowest total price we could find by $2. (We saw it for $8 less in November, since expired.) Wii MotionPlus purports to track players' movements in finer detail and with greater accuracy than the Wii hardware alone. It can only be used with specially designed games.

Of note, Walmart still has it for $16.54 with free Site-to-Store. However, Walmart charges sales tax in more locations.
