Coupons allow staff to create codes that can be used by Community Hub users to receive dollar amount or percentage-based discounts on eligible order items. The checkout page will show a Coupon card if there are active coupon codes for the primary entity and the current cart is over $0. Coupons are created as products in staff view, with coupon rules with discount values defined within the product.
Only one coupon code can be used per order. Also, if the coupon code is related to a specific product, and there are more than one of that product in the cart, the coupon code is applied to the product with the greatest cost.
