Newegg offers the refurbished 3.4-lb. Acer CB3-431-C5EX Intel Braswell Celeron 1.6GHz 14" 1080p Chromebook in Sparkly Silver for $179.99 with free shipping. (Monoprice offers a similar model for the same.) That's $15 under our February refurb mention and the lowest price we've seen. (It's the best deal for a refurb today by $20.) It features an Intel Celeron N3160 1.6GHz Braswell quad-core processor, 1920x1080 (1080p) IPS LCD, 4GB RAM, 32GB SSD, 802.11ac wireless, Bluetooth 4.2, webcam, 3-cell battery, and Chrome OS. Deal ends May 16.
Note: A 90-day warranty applies, although it's unclear who backs it.
