Dell Home offers the Vizio D-Series 50" 4K 2160p LED-Backlit LCD Ultra HD Smart Television model no. D50U-D1, bundled with a $200 Dell eGift Card, for $549.99 with free shipping. (The gift card is automatically added to your cart and will arrive via email 10 to 20 days after ship date.) Assuming you'll use the gift card, that's a $50 drop from yesterday's mention and the lowest total price we've seen. (The gift card also makes it a low today by $150, although most retailers charge $549 or more.) It features a 3840x2160 (4K) native resolution, 802.11ac wireless, Vizio Internet Apps Plus (with access to Netflix, Hulu Plus, Pandora, etc.), USB, and five HDMI inputs. Deal ends June 2.
