Best Buy via eBay offers the open-box 3.9-lb. Dell Inspiron 13 Intel Kaby Lake Core i5 2.5GHz 13.3" 1080p 2-in-1 Touchscreen Laptop for $509.99 with free shipping. That's $120 less than our mention of a new, factory-sealed unit from two days ago and the lowest price we've seen for this laptop. (It's $90 less than what Best Buy charges now for the factory-sealed system.)
It features an Intel Core i5-7200U 2.5GHz Kaby Lake dual-core processor, 13.3" 1920x1080 (1080p) touchscreen LCD, 8GB RAM, 256GB SSD, Bluetooth 4.2, HDMI, USB 3.0, and Windows 10 Home 64-bit.
