At Dell Home, search for "A6937583" to find the Samsung 51" 600Hz 1080p Widescreen Plasma HD Television
(pictured), model no. PN51E530, bundled with a $300 Dell gift card
with free shipping
. That beats our mention from two days ago (which only included a $150 gift card) and assuming you use the credit, it's the best price we've seen for a Samsung 51" 1080p plasma HDTV. (It's also current price low by $316, when factoring in the credit.) Features include a native resolution of 1920x1080 (1080p), 600Hz subfield drive, USB port, two HDMI inputs, and more. Deal ends May 19.
Of note, the gift card will be sent via email 10 to 20 days after purchase.
