How we measure this
- Same product means the same barcode (GTIN) across shops, from retailers' own product feeds.
- Prices include delivery. Only in-stock offers seen in the last 3 days count; marketplace sellers are left out.
- Gaps above 60% are left out as likely listing mismatches. A gap needs £5 and 5% to be listed. Everyday prices only (up to £3,000).
- Ranking is never paid for. Always check the final price on the retailer's site before you buy.
- Free to reuse with a link to this page. Data as JSON: /api/price-gaps.
