Walmart offers the refurbished Vizio 49" 4K LED-Backlit LCD Ultra HD Smart Television, model no. M49-C1, for $349.99 with free shipping. That's $21 under our June mention of a refurb and is the best outright price we've seen for this TV in any condition. (It's the best deal for a refurb today by $19.) It features a native resolution of 3840x2160 (2160p), 120Hz refresh rate, full-array LED backlight, 802.11ac dual-band wireless, Ethernet, 4K upscaling, Internet apps (Netflix, Hulu, Pandora, etc.), USB, and five HDMI inputs.

Note: A 90-day warranty applies, but it's not clear who backs it.
