Terms of the previous offer
- Costco marked the exact item out of stock on 27 July 2026; do not rely on the previous lower checkout total unless the offer returns.
- This exact QD006W version has a 1920x1200 60Hz OLED screen. Some generic Vivobook S 14 copy mentions a 3K 120Hz panel, but that is not the panel listed for this configuration.
- The 16GB memory is the maximum listed for this Lunar Lake configuration, so choose a 32GB model instead if you expect heavy virtual-machine, local-AI or large creative workloads.
- The listing says backlit keyboard but does not explicitly state the physical UK layout or charger contents. Check the product images and box contents if either matters.
Why the previous offer stood out
- The lower checkout price is competitive for a light 14-inch OLED laptop with a recent Core Ultra 7 processor, 16GB RAM and a 1TB SSD.
- The exact Costco specification lists a 600-nit, 100% DCI-P3 OLED panel, Wi-Fi 7, two Thunderbolt 4 ports and a 75Wh battery in a 1.3kg chassis.
- Intel's Core Ultra 7 256V includes Arc 140V integrated graphics and a 47-TOPS NPU, making this a capable Copilot+ productivity laptop without a dedicated-GPU weight penalty.
