Sears offers the Panasonic VIERA 55" 1080p 3D Widescreen Plasma HD Television, model no. TC-P55ST30, for an in-cart price of $999.88 with free shipping. (You must sign in or create a free account to see this price.) That's the lowest total price we could find by $88, outside of the price below, although we saw it for a buck less last week (since expired). It features a 1920x1080 (1080p) native resolution, 600Hz sub-field drive, Ethernet and USB connectivity, VIERA Connect (with Netflix, Amazon Instant Video, CinemaNow, and more), three HDMI inputs, and other video inputs.

Note: 3D glasses are required for viewing 3D content (not included).

A close price: TigerDirect has it for $999.99 with free shipping.
