Walmart offers the ProGear Freedom Stride Air Walker Elliptical for $79 with free shipping. That's the lowest price we could find by $17. It features a 48" stride length and six tension levels and eliminates impact on your back, knees, ankles, and feet. It also folds for storage, so you'll never end up using it as a clothing tree.

Update: The price now drops to $74.97 with in-store pickup.
