Walmart offers the RCA 50" 4K 2160p LED-Backlit LCD Ultra HD Television, model no. RLDED5098-UHD, for $299.99 with free shipping. That's the lowest price we could find by $50, although we saw it for $10 less in April. It features a 3840x2160 (2160p) native resolution, LED backlight, and three HDMI inputs.
