Walmart offers the RCA 65" 4K Flat LED Ultra HD Smart Television, model no. RNSMU6536, for $499.99. Opt for in-store pickup to dodge the $49.97 shipping fee. That's $500 off and the lowest price we could find, although it was a buck less in September. Features include a 3840x2160 (4K) native resolution, WiFi streaming, and three HDMI inputs.
