“…These reviewed theories offer various explanations as to the effectiveness of promotions beyond price reduction Ten years after Sawyer and Dickson (1984), it can still be said that they are reasonably complementary On one hand is the robust multi-attribute model of attitude change suited to extensive information processing situations It could be extended to other involved promotions like loyalty programmes One important and not yet resolved issue is the postulate of cognitiveevaluative-behavioural sequence Knowing that the costs of clipping coupons are perceived as being lower for more frequent users of coupons (Jolson et al 1987;Tat 1994) does not indicate whether beliefs cause behaviours or the reverse Generally speaking, our knowledge of consumers' beliefs about promotions and promoted products is very poor Further research is needed to investigate their beliefs about the amount of effort necessary, the sincerity of the sponsor and his motivations (Alpert 1993;Froloff 1993;Tat 1994) Turning to deal-proneness, future research could link the two types of deal-proneness with each consumer's conception of value (Zeithaml 1988) However, by articulating the distinction between couponproneness and value-consciousness, attitude research has demonstrated the limits of its earlier postulates of a rational consumer On the other hand, scholars have proposed the notions of signal, schema and script, as well as behavioural learning theories that are suited to succinct information processing situations These models deserve future research Specifically, we have medium involvement situations in mind, where promotional signals can serve to attract consumers' attention, which would in turn result in the brand entering the consideration set and its information being centrally processed Besides, consumer behaviour theories adapted to routine purchases like the Hoyer Purchasing Tactic Model (1984) would benefit from explicit account of sales promotions Finally, behavioural theories, and especially recent ones (Shimp 1992), deserve further attention since they have highlighted one of the major long-term issues of sales promotions: do they teach people to buy products on sale?…”
