Terms of the previous offer
- Costco membership is required, and the previous £679.99 total depended on a £270 automatic basket reduction from the visible £949.99 price. The reduction was not reverified on 30 August, so do not rely on it unless your basket reproduces the lower total.
- The Ryzen AI 5 430 is a four-core processor with entry-level integrated Radeon graphics. It is suitable for everyday productivity but not a strong choice for demanding rendering, large software builds or modern gaming.
- Costco lists the laptop at 0.94kg, an unusually low figure for this 14-inch chassis. Confirm the exact weight if sub-1kg portability is central to the purchase.
- The product description says the OLED panel reaches up to 600 nits, while Costco's specification table lists 400 nits. Treat 400 nits as the safer expectation and confirm the exact panel before buying for colour-critical or bright-room work.
- The listing says backlit chiclet keyboard but does not explicitly confirm the physical UK layout. Check the keyboard shown in the final order and inspect the delivered unit promptly.
- The 16GB LPDDR5X memory is likely soldered and no upgrade route is stated on the exact offer; buy enough memory for the laptop's expected lifetime.
Why the previous offer stood out
- A 29 August basket check reproduced an automatic £270 reduction and £679.99 total, but that lower total was not reverified on 30 August.
- 16GB LPDDR5X memory, a 1TB SSD and a 14-inch 1920x1200 OLED display make the core specification practical for office work, study, media and travel.
- The retailer lists a 68W USB-C power adapter, Wi-Fi 6E, USB4, HDMI, a backlit keyboard and a two-year warranty, so the package is more complete than many thin laptops that omit a charger.

Condition, warranty and price evidence
- Condition
- New
- Warranty
- Costco lists a two-year warranty for this exact new laptop. Confirm the written cover and returns terms with the order.
- Eligibility
- Costco membership is required. The exact item still displays £949.99, but the previous automatic £270 reduction and £679.99 basket total were not reverified on 30 August. Do not rely on the lower total unless it appears again in your basket.
- Recorded availability
- Rechecked on 2026-08-30: exact Costco item 638705 remained InStock at a visible £949.99, but the local basket route was unavailable and the previous £270 reduction could not be reproduced. The lower total is not a current recommendation pending a fresh basket check.
