The arithmetic of a sale price (a percentage off, an extra percentage off the reduced price, the original price worked back) is pure maths and lives in compute.js; this table holds only what the law says about the price a reduction is measured against, per country. reference_price.rule is 'lowest-in-period' (France: the 'prix antérieur' shown with any announced reduction is the lowest price charged to all consumers during period_days days before the reduction; for successive reductions during a set period it stays the price before the first reduction) or 'genuine-usual-price' (United Kingdom: no fixed period in the Act or in the CMA's guidance; the higher price in a price reduction claim must be a genuine and realistic selling price, the product's usual selling price). sales_periods (France only) is quoted by the page content, not read by the handler. Table-level valid_from/valid_until bound the period during which this version may be relied on: neither rule has a scheduled change, so valid_until is a review date. Entry-level valid_from/valid_until bound each rule; a null valid_until means in force until changed. source_url is the primary source, source_date that source's own date (the date the version in force took effect, or the page's last-updated date), retrieved the date the value was read there.", "reviewed_on": "2026-11-11", "reviewed_by": "apps-calculators agent (automated research against official sources, 2026-11-11); owner review pending", "valid_from": "2026-11-11", "valid_until": "2027-06-30", "locale_country": { "fr-FR": "FR", "en-GB": "GB" }, "countries": { "FR": { "name": { "fr-FR": "France", "en-GB": "France" }, "currency": "EUR", "reference_price": { "rule": "lowest-in-period", "period_days": 30, "successive_reductions": "price-before-first-reduction", "not_covered": { "fr-FR": "les produits périssables menacés d’une altération rapide, et la comparaison avec les prix d’autres professionnels", "en-GB": "perishable goods at risk of rapid deterioration, and comparisons with other traders’ prices" }, "summary": { "fr-FR": "Toute annonce d’une réduction de prix indique le prix antérieur : le prix le plus bas pratiqué à l’égard de tous les consommateurs au cours des 30 jours précédant la réduction.
