Dell Home, via its Member Purchase Program, offers the Vizio D-Series 50" 1080p LED-Backlit LCD HD Smart Television, model no. D50-D1, bundled with a $100 Dell Gift Card, for $349.99 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 effectively tied with our mention from September (which had a higher base price but also a larger gift card) as the best price we've seen for this TV. (It's a low today by $108, after factoring in the credit.) It features a native resolution of 1920x1080 (1080p), 802.11n wireless, Ethernet, Vizio Internet Apps Plus (with access to Netflix, Hulu Plus, Pandora, etc.), USB, and three HDMI inputs.
Note: Dell's MPP is available to select groups, including students, government employees, military (active and retired), credit union members, and health care workers.
