Dell Home offers the Samsung 55" 4K 2160p LED-Backlit LCD Ultra HD Smart Television, model no. UN55KU6290, for $549.99 with free shipping. (PC Richard & Son charges the same.) That's tied with our mention from last week and the lowest total price we've seen. (It's the best deal now by $150, although most stores charge around $800.) It features a 3840x2160 (2160p) native resolution, internet apps, WiFi, USB, Ethernet, and three HDMI inputs.

Update: The price has increased at Dell Home; however, PC Richard & Son still offers it for $549.97 with free shipping.
