Buy conditions are the promotion’s eligibility rules that determine the transactions that qualify for the promotion. A promotion can only be applied to a transaction that meets the requirements specified by the eligibility rules.
You choose which customers are eligible for the promotion, specify locations or websites that are eligible, or if the order itself must meet specific criteria to be eligible for the promotion, or a combination of all the preceding factors. Criteria can include items that the customer must buy or a minimum amount that the customer must spend, or both. Item promotions for example, can contain eligibility criteria for a minimum order amount and a specific item or items. A transaction will be eligible for a promotion’s discount only if it meets all of the defined eligibility criteria.
You can create promotions that do not have any Buy conditions.
Buy conditions are defined in the What the Customer Needs to Buy section.
