Why these prices?
- We compare this exact variant only: same brand, scent, concentration, size, packaging, pack count and condition.
- Every price is a delivered total for the same delivery context — your area and Prime setting — including VAT and known fees.
- If a delivery charge, fee or stock level is unknown, the offer is shown separately and never used for a saving.
- Prices older than 876000 hours, or checked too far apart, don’t produce a saving.
- Voucher codes for first orders, app-only offers, cashback and loyalty points are listed separately, not subtracted.
- The cheapest verified delivered price ranks first even when it pays us nothing.
Catalogue identity researched 8 October 2026 from public listing information. That is separate from when prices were last checked.
