A four-item semantic differential scale assessing a consumer's perception of how exclusive or restricted a price promotion or deal is. Items span availability (few vs. many customers), the exclusive-inclusive continuum, degree of restriction, and selectivity. The scale was designed as a manipulation check to verify that promotional exclusivity manipulations were perceived as intended, though its strong reliability and face validity make it applicable as a substantive measure in studies where perceived deal exclusivity is theoretically relevant.
