For its members, Sam's Club offers the ProForm Performance 900i Treadmill for $898 with free shipping. (Non-members pay an extra $89.80, so it's better to buy a 1-year membership for $45.) That's the lowest price we could find by $36. It features a 10" smart HD touchscreen display, 30 on-board workouts, and foldable design. Deal ends July 16.
