Compare unit prices fairly
Two 500 g bags and one 800 g bag are hard to compare by sticker price. Divide the final cost by the total amount to compare on a 100 g basis.
Final total = Price × paid quantity → apply discount and round down to whole KRW → deduct fixed coupon (minimum KRW 0) → add shipping
Unit price = Final cost ÷ total amount including free items × reference quantity
How 1+1 and 2+1 offers work
1+1 gives one free item for every paid item; 2+1 gives one free item for every two paid items. With 2+1, buying three gives one free item, four in total. Check quantities if the seller uses different rules.
Check coupons and shipping
The discount applies first, then one fixed coupon is deducted. Minimum spend, maximum discount and membership rules aren't checked automatically; enter an eligible amount. Allocate shipping to each product yourself.
Do not mix weight, volume and count. Quality, ingredients and usage may make a higher-priced product more suitable. This comparison considers price only.
