Walmart offers the TCL 40" 1080p LED-Backlit LCD HD Television, model no. LE40FHDE3010, for $249 with free shipping. (Amazon offers it for the same.) That's the lowest total price we could find for new unit by $50. (It's also $31 under the best price we could find for a refurb.) Features include a 1920x1080 (1080p) native resolution, 60Hz refresh rate, and three HDMI inputs.

Update: It's now sold out at Walmart; however, Amazon still offers it for $248.88 with free shipping. Note that it's currently on backorder with an estimated ship time of one to three weeks.
