Create discount promise without pre-added coupon
The discount promise without a pre-added coupon is a method in which the discount is applied to a transaction without the need for a coupon already linked to the user's account or transaction.
In this case, the discount can be automatically applied based on certain criteria or actions, such as customer loyalty, total purchase value, or participation in a specific promotion.
Unlike the approach with a pre-added coupon, where the discount is guaranteed through a code already entered, here the discount is ensured through rules or conditions defined by the platform or the seller. This strategy allows customers to benefit from discounts without the need to enter codes.
