Discount
The shopping mall provides codes or coupons that let consumers receive benefits, and using them lets consumers purchase products at a discounted price. Coupons are provided in two forms, general discount coupons and free-shipping coupons, and these benefits are used as a marketing tool to draw consumer interest and encourage more purchases.
Key Features
Applying coupons and discounts
Members can purchase products using the various coupons and discounts provided by the shopping mall.
A variety of coupons and promotions
The shopping mall offers many kinds of coupons and promotions, providing members with a wide range of discount benefits.
Discount types
Two types of discounts are provided when applying a discount benefit: fixed-amount benefits and percentage-rate benefits.
Margin check
When applying a discount benefit, a margin check restricts discount benefits larger than the supply cost, minimizing losses for the company's own products.

Benefit
The applicable benefit for each tier is calculated based on whether it is a percentage-rate or fixed-amount benefit.
Benefits are applied across a total of three tiers, and one coupon or discount benefit can be received per tier.
To prevent losses to the company, when a benefit is applied, coupon and discount benefits are restricted if the result is cheaper than the product's supply cost.
