Canon offers its factory-refurbished Canon PowerShot SX50 HS 12.1-Megapixel Digital Camera in Black, model no. 6352B001, for $179.99 with free shipping. That's $20 under last week's mention and the lowest total price we've seen for this model. (It's $169 less than a new one.) It features a 2.8" LCD, 50x optical zoom, 1080p video recording, optical image stabilization, 24mm wide-angle lens, and SDXC card slot. A 1-year Canon warranty applies. Deal ends December 31.
