Dell Home offers the Vizio 55" 240Hz 1080p WiFi LED-Backlit LCD Smart HD Television, model no. M552I-B2, bundled with a $100 Dell eGift Card for $597.99 with free shipping. (The gift card will be emailed to you 10 to 20 days after purchase.) Assuming you'll use the gift card, that's $100 under last week's mention and the lowest total price we've seen for a new unit. (It's also a current low by $143.) It features a 1920x1080 (1080p) native resolution, 240Hz refresh rate, LED backlight, WiFi, VIZIO Internet Apps with Netflix, Amazon Instant Video, and Hulu Plus, and four HDMI ports. Deal ends June 1.
