Walmart offers the factory-refurbished Hisense 55" 120Hz 1080p 3D LED-Backlit Widescreen LCD HD Television, model no. LTDN55T39XWUS3D, for $599.98. Opt for free Site-to-Store pickup to avoid the $44.97 shipping charge. At $150 off, that's tied with our expired mention from last week and still the least expensive 55" 120Hz 1080p LED-backlit LCD TV we've seen with WiFi. Sales tax is added where applicable. It features a native resolution of 1920x1080 (1080p), 120Hz refresh rate, LED backlight, 100,000:1 dynamic contrast ratio, 400 cd/m² brightness, 8ms response time, built-in WiFi, four HDMI inputs, and other video inputs.

A 90-day warranty applies; however, it is unclear who supports it.
