Shoppers often compare price per jin to evaluate bulk offers and wholesale discounts. By dividing the total price by the number of jin, you can directly compare stalls and online stores on a consistent basis.
Impact on Small Businesses
For small vendors, clear jin-based pricing builds trust with customers. Transparent scales and visible price tags per jin reduce negotiation friction and support steady, repeat business in competitive marketplaces.
