Newegg offers the refurbished Samsung 50" 1080p WiFi LED-Backlit LCD HD Television, model no. UN50F5500, for $524.99 with free shipping. That's $25 below last month's refurb mention and the lowest total price we've seen. (It's a current low of $190 for a refurb.) It features a native resolution of 1920x1080 (1080p), WiFi, Smart TV with Samsung Apps (including Netflix, YouTube, Hulu Plus, and more), USB, and four HDMI inputs.

A 90-day warranty applies, although it's unclear who backs it. If you haven't yet, pay with Google Wallet via Newegg's iPhone app to knock the price to $509.99. (It can only be redeemed once per account.)
