Walmart offers the RCA 50" 4K Flat LED Ultra HD Television, model no. RLDED5098-UHD, for $239.99 with free shipping. That's tied with our mention from ten days ago and the lowest price we could find by $80. (For further comparison, it was $20 less in November.) It features a 3840x2160 (4K, 2160p) native resolution and four HDMI inputs.
