Terminology
Discount Type (Fixed Amount)
A type of coupon that discounts a set amount or amount range when a product is purchased. This type of coupon mainly discounts a fixed amount, or provides a benefit that discounts the amount specified at the time of registration once a minimum purchase amount is met.
Discount Type (Percentage)
A coupon that discounts a certain percentage of a product's price when the product is purchased. With this type of coupon, the discounted amount varies according to the product's price. Because a percentage coupon causes the discounted amount to vary relative to the product's price, the higher the product's price, the greater the discounted amount can be.
Issuance Count per Member
Specifies the maximum number of times a single member can receive the coupon.
Total Issuance Count
Specifies the total issuance count for the coupon. First-come, first-served coupon issuance is possible up to the set number.
Issuing Entity
Fixed Promotional Coupon: A coupon provided on a fixed basis for promotional purposes. Event Coupon: A coupon created for a specific event. Partner: A coupon created for a specific partner's products. Customer Compensation Coupon: A coupon created to compensate a customer claim.
Other Notes
Targeted Issuance: A system that automatically issues a coupon to specific members.
Conditional Automatic Issuance: A system that automatically issues a coupon, via a daily batch, to members who meet specific set conditions.
Customer Download Issuance: A system in which customers directly obtain the coupon from within the shopping mall pages.
Cost Share Ratio: A system that coordinates the cost incurred from the coupon between the company and its partner.

Discounts can be applied in 1-won increments, and any amount under 1 won is rounded.
Promotions are recalculated only when a claim is filed before all products in the order have shipped.
To prevent a 0-won payment, coupons/discounts with a discount amount greater than the selling price cannot be used.
