The finding
Of the 140 model-level offers, 114 were marked in stock when checked, 24 were out of stock and 2 had unknown availability. The recorded prices ran from £24.99 to £1,299.00, with a median of £189.99.
Those totals need context. The catalogue contains exactly 20 models in each category, but only 9 named retailers across the whole snapshot. Several categories come mainly from a manufacturer shop or one specialist retailer. The data is therefore useful for tracking a known exact-model offer, not for claiming the lowest price available in the UK.
No recorded offer was affiliate-active at the time of the study. Price, stock and merchant identity remain separate from the category score. A product can rank first and still be unavailable at its tracked retailer.

Method and limits
- We used one stored offer per exact model from the validated catalogue checked 27 Jul 2026, 22:04 BST.
- Prices are the recorded listed prices. Delivery costs, membership prices, coupons and later price changes are not normalised into the study.
- The median is the middle recorded price within each 20-model category. It is descriptive, not a recommended budget.
- Availability is the retailer observation stored at the checked time. Page render time does not refresh it.
- One offer per model cannot establish the cheapest retailer or a complete view of UK availability.
