Western Digital again offers its factory-refurbished Western Digital My Cloud 4TB NAS, model no. WDBCTL0040HWT-NESN, for $154.99 with free shipping. That's tied with our mention from last week as the lowest total price we've seen in any condition. (It's $30 under a new one today.) It features USB 3.0, Gigabit Ethernet, WD SmartWare Pro backup software, and password protection. A 6-month Western Digital warranty applies.
