Walmart offers the refurbished Sony 48" WiFi LED-Backlit LCD Smart HD Television, model no. KDL-48R510C, for $279.99 with free shipping. That's tied with our mention from last week as the lowest price we've seen. (It's also $100 less than what you'd pay for a new unit.) It features a 1920x1080 (1080p) native resolution, WiFi, Smart TV features (with access to Netflix, Hulu Plus, and other Sony internet apps), USB, and two HDMI inputs.
