Como funciona

1. Create a coupon on the Coupons page and share its Code.
2. At checkout, the customer enters the code on their order.
3. Casdoor validates the coupon — scope, validity window, minimum order amount, quantity, and per-user usage limit — and applies the discount to the order total.

Each redemption is recorded so that quantity and per-user usage limits are enforced.
