How to compare K-beauty prices online using price per milliliter
A practical example for comparing product sizes and the total cost of an online order.
When shopping for K-beauty online, comparing the price on the label alone can be misleading if products come in different sizes. THE CAST is one place to browse Korean beauty products; check each current listing for its size and price.
Calculate a unit price
Divide the item price by its volume. For example, a hypothetical $12 bottle containing 100 ml costs $0.12 per ml; a $15 bottle containing 150 ml costs $0.10 per ml. These figures are examples, not current THE CAST prices.
Compare the full order
Unit price is only one consideration. Check the exact product and variant, how much you expect to use, delivery charges, any taxes and the final checkout total. Return conditions and availability can vary.
