Sam's Club offers its members the 5.1-lb. Lenovo Edge 2 1580 Intel Skylake Core i7 2.5GHz 15.6" 1080p 2-in-1 Touchscreen Laptop in Ebony Black, model no. 80QF0006US, for $549 with free shipping. (Non-members must pay a $54.90 surcharge, so it's better to sign up for a 1-year membership for $45.) That's $20 under our mention from two weeks ago and the lowest total price we've seen. (It's the best deal today by $51.) It functions as a laptop or tablet and features an Intel Core i7-6500U 2.5GHz Skylake dual-core processor, 15.6" 1920x1080 (1080p) IPS LED-backlit touchscreen LCD, 8GB RAM, 1TB hard drive, 802.11ac wireless, Gigabit Ethernet, Bluetooth 4.0, HDMI, USB 3.0, backlit keyboard, 3-cell battery, and Windows 10 Home 64-bit.
