In the field of sales promotion, the acronym CSOA is often used to refer to a “Free Gift with No Purchase Obligation.” CSOAs are offered as part of mail-order sales, giving recipients the opportunity to receive a gift without necessarily making a purchase (usually by covering the shipping costs). Furthermore, CSOAs are also used to attract customers to physical stores, where they are notified by phone that they can come to the store to collect their gift. Once there, they naturally receive assistance from a sales associate.
