  • 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.
