Sears offers the Seiki 55" 4K 2160p LED LCD HD Television, model no. SE55UY04, for $799.99. Opt for in-store pickup to dodge the $69.99 shipping fee. That's tied with our mention from last week and the lowest price we could find for any 55" 4K TV, although we saw this one for $40 less a month ago. It features a 3840x2160 native resolution, 120Hz refresh rate, LED backlight, and three HDMI ports.
