Newegg offers the 4.9-lb. refurbished Asus Intel Haswell Core i5 1.7GHz 15.6" 1080p 2-in-1 Touchscreen Laptop, model no. Q502LA-BBI5T12, for $429.99. This $30 mail-in rebate cuts it to $399.99. With free shipping, that's $100 under our March refurb mention and the lowest total price we've seen. (It's also $99 below the best price we could find for a new one.) It features an Intel Haswell Core i5-4210U 1.7GHz dual-core processor, 15.6" 1920x1080 (1080p) touchscreen LCD, 8GB RAM, 1TB hard drive, webcam, 802.11ac wireless, Gigabit Ethernet, Bluetooth 4.0, and Windows 8.1 64-bit. (No optical drive is included.) Rebate expires August 31.
Note: A 90-day warranty is applied, although it's unclear who backs it.
