Walmart offers the Gold's Gym Trainer 430i Treadmill with Heart Rate Monitor for $377 with free shipping. (Jet.com offers the same price.) That's tied with our March mention and the lowest price we could find by $23. It features an LCD display, 16" x 50" tread belt, iFit technology, power incline, and a dual-grip heart rate monitor.

Update: The offer at Walmart has ended; however, Jet.com still has it for $377 with free shipping.
