Walmart offers the Samsung 55" 4K 2160p WiFi LED-Backlit LCD Ultra HD Smart Television, model no. UN55JU6400FXZA, for the in-cart price of $699.99 with free shipping. (Amazon charges the same.) That's tied with our mention from a week ago and the best deal we could find now by $198. (It's also tied as the best outright price we've seen.) It features a 3840x2160 (2160p) native resolution, built-in WiFi, Smart TV apps (including Hulu Plus, Netflix, YouTube, and more), USB, and three HDMI inputs.
