Coupons & Activity Pricing

Updated: 2026-03-28

Dujiao-Next provides two promotional mechanisms: Coupons (manually entered by users) and Activity Pricing (automatically applied when conditions are met). Both can be stacked with membership level discounts.

1. Discount Application Order

When a user places an order, the system calculates the final price in the following order:

Base price (or SKU price)
    |
Membership level discount (auto-applied)
    |
Activity pricing (auto-applied when conditions are met)
    |
Coupon discount (manually applied by user)
    |
Final payment amount

Activity pricing and membership pricing use whichever is lower; coupons are then applied on top of the activity price.

2. Coupons

2.1 Coupon Types

Type	Identifier	Calculation
Fixed amount discount	fixed	Deducts a fixed amount from the order
Percentage discount	percent	Deducts a percentage of the order amount

2.2 Creating Coupons

Create coupons from the "Coupons" page in the admin panel. Configuration options include:

Field	Description
Coupon Code	Unique identifier that users enter to apply the coupon
Discount Type	fixed (fixed amount) or percent (percentage)
Discount Value	The fixed amount or discount percentage
Minimum Spend	The subtotal of eligible products must reach this amount
Maximum Discount	Upper limit on discount amount for percentage-type coupons
Total Usage Limit	Maximum number of uses site-wide; 0 for unlimited
Per-User Limit	Maximum number of uses per user; 0 for unlimited
Applicable Products	Specify which products the coupon applies to (all or selected products)
Validity Period	Start time and end time
Enabled	Toggle on/off

2.3 Usage Rules

When a user enters a coupon code at checkout, the system validates in this order:

1. Does the coupon code exist and is it enabled?
2. Is the current time within the validity period (start time <= now <= end time)?
3. Has the site-wide usage limit been reached?
4. Has the current user's usage limit been reached (registered users only)?
5. Does the subtotal of eligible products meet the minimum spend requirement?

Discount Calculation:

• Fixed amount: Deducts the specified amount directly
• Percentage: Calculates the percentage of the eligible products' subtotal, capped by the "Maximum Discount" limit
• The discount amount will never exceed the subtotal of eligible products

2.4 Applicable Scope

The coupon's "Applicable Products" setting determines which products participate in the discount calculation:

• Only the subtotal of in-scope products is used to evaluate the "Minimum Spend" requirement
• Only in-scope product amounts are included in the discount calculation
• Products outside the scope in the same order are unaffected

3. Activity Pricing

3.1 Activity Pricing Types

Type	Identifier	Calculation
Percentage discount	percent	Unit price = original price x (100 - value) / 100
Fixed amount discount	fixed	Unit price = original price - value (minimum 0)
Special price	special_price	Unit price = specified value

3.2 Creating Activity Pricing

Create activity pricing rules from the "Activity Pricing" page in the admin panel. Configuration options include:

Field	Description
Name	Activity name (supports multiple languages)
Applicable Products	Specify which products the rule applies to
Discount Type	percent / fixed / special_price
Discount Value	The numeric value for the corresponding type
Threshold Amount	The purchase subtotal (unit price x quantity) must reach this amount for the rule to take effect
Validity Period	Start time and end time
Enabled	Toggle on/off

3.3 Tiered Discounts

Multiple activity rules can be configured for the same product to create tiered discounts:

Rule A: Threshold $50, discount 1%
Rule B: Threshold $150, discount 2%
Rule C: Threshold $500, discount 5%

The system matches thresholds from highest to lowest, applying the highest tier whose condition is met:

• Purchase subtotal $49 -> No discount
• Purchase subtotal $100 -> Matches Rule A (1%)
• Purchase subtotal $200 -> Matches Rule B (2%)
• Purchase subtotal $600 -> Matches Rule C (5%)

3.4 Application Logic

• Activity pricing is matched on a per-product basis; each product is calculated independently
• The system displays activity rules on the product detail page, even if the current quantity does not meet the threshold
• Price precision is two decimal places
• Activity pricing rules of the same type do not stack; the best matching rule is used for each product

4. Best Practices

• Coupons are well suited for flash sales, new user acquisition, and targeted product promotions
• Activity pricing is ideal for tiered pricing and bulk purchase discounts
• Both can be used simultaneously: activity pricing automatically reduces the unit price, and coupons provide an additional reduction on top
• It is recommended to periodically clean up expired coupons and activity pricing rules to keep lists manageable
