A four-item scale measuring consumer scepticism toward a specific sales promotion — the degree to which the promotion is perceived as deceptive, gimmicky, and designed to extract payment through hidden means. Items assess beliefs that the customer will ultimately pay in ways they are unaware of, that the promotion is misleading, that it is a marketing trick, and that there are ulterior motives behind the offer. The scale captures negative inferential responses to promotional framing and is applicable to research on consumer scepticism, price promotions, and retail marketing.
