Sears offers the Seiki 50" 4K2K 2160p LED LCD HD Television, model no. SE50UY04, for $699.99. Choose in-store pickup to dodge the $69.99 shipping fee. That's a $60 drop from two weeks ago and the lowest total price we've seen for this TV by $22. (It's a current low by $70, but most stores charge well over $1,000.) It features a 3840x2160 resolution — four times that of 1080p TVs. It also has a 120Hz refresh rate, LED backlight, and three HDMI ports.
