Knowledge Base & Operational DocumentationWhy Does CS-Cart Show a Coupon as Applied but Not Change the Order Total?
A coupon can appear in the cart while producing no discount if its conditions are unmet, its value is zero for the selected products, or another promotion takes precedence. The interface may not explain the eligibility rule clearly.
What to check
Check coupon dates, customer group, product and category restrictions, minimum order, usage limit, currency, promotion priority, and discount calculation logs. Reproduce with a cart that meets each condition individually.
Recommended next step
Correct the rule or improve the eligibility message based on intended policy. Test both qualifying and nonqualifying carts and verify the order summary matches the final amount charged.
