Walmart again offers the refurbished Sony 48" WiFi LED-Backlit LCD Smart HD Television, model no. KDL-48R510C, for $299.99 with free shipping. That's tied with our mention from a week ago as the lowest total price we've seen. (It's also $80 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.
Note that no warranty information is provided.
