Update: Walmart is no longer accepting pre-orders.Walmart.com is the first store to have the unbelievable Wii Fit available for pre-order. It is $89.74 plus you get a $10 Walmart gift card if you order by 5/11. Shipments are expected to begin on 5/21. Aside from saving 25¢ off the expected $89.99 retail price, the $10 gift card offer is likely the best you'll see with this for a while. Shipping, however, will cost $11.97 and tax is charged to most states (stores that normally have more friendly shipping costs aren't offering pre-orders, yet). Wii Fit and the included Wii Balance Board are designed to get you hooked on fitness by doing aerobics, yoga, muscle stretches and balance oriented games on your Wii. You can setup daily workouts, track your progress or monitor your BMI (body mass index).
