Walmart offers the RCA 43" 4K Flat LED Ultra HD Television for $179.99 with free shipping. That's tied with last week's mention as the lowest price we've seen and the best price we could find today by $40. (It's also tied as the second-best price we've seen for any 43" 4K TV.) It features a 3840x2160 (4K) native resolution and four HDMI inputs.
