How to choose: K18

K18: the most compared products, the best value per 100 ml and today’s biggest price cuts — based on prices incl. delivery from the shops we track.

  • Compare the price per 100 ml, not the price of the pack — a bigger bottle is often, but not always, better value.
  • Check the price incl. delivery: a cheaper product with paid delivery often loses to a pricier one with free delivery.
  • Before a sale, look at the 30-day price history on the product page — it shows whether the discount is real.
  • Not in a hurry? Set a price alert — we e-mail you once when the price drops to your amount.
