Dell Home offers the Vizio D-Series 49.5" 4K 2160p LED-Backlit LCD Ultra HD Smart Television, model no. D50-E1, bundled with a $100 Dell Gift Card for $499.99 with free shipping. (The gift card will arrive via email 10 to 20 days from ship date.) Assuming you'll use the gift card, that's the lowest price we could find by $78, although we saw it for the same price bundled with a $150 gift card last week. It features a 3840x2160 (4K, 2160p) native resolution, full-array LED backlight, 802.11ac wireless, Vizio Internet Apps Plus (Netflix, Hulu Plus, Pandora, etc.), USB, and four HDMI inputs. Deal ends August 21.
