Costco offers its members the 3.8-lb. Acer Swift 3 Intel Kaby Lake R Quad Core i5 1.6GHz 14" 1080p Laptop for $549.99 with $14.95 for shipping. (Non-members pay $35 more.) That's $165 under our September mention of a similar build and $115 under the best price we could find for a comparable configuration elsewhere. It features an 8th-generation Intel Core Kaby Lake R i5-8250U 1.6GHz quad-core processor, 14" 1920x1080 (1080p) IPS LED-backlit display, 8GB RAM, 256GB SSD, 802.11ac wireless, Bluetooth 4.0, backlit keyboard, 4-cell battery, and Windows 10 Home 64-bit. Deal ends December 24.
