Long-term effects of discounts and free-product promotions on value perceptions ─ Why less promotion is sometimes more

Pricing is an essential element when it comes to marketing and selling goods and different price promotions are widely used tools to attract and retain consumers. However, the expected positive impacts of such price promotions on consumer perceptions have been increasingly questioned in recent years. In particular, with regard to quality perceptions and internal reference prices, a number of past research findings suggest that monetary price promotions might be more likely to result in unfavourable consumer perceptions than non-monetary promotions (Diamond & Campbell, 1989; Darke & Chung, 2005). Instead of only focusing on the short-term effects of different promotion methods, the aim of this study is to examine the long-term effects of the use as well as the choice of price promotions on consumers’ value perceptions. Using an internet-based survey, subjects’ long-term willingness to pay for three non-durable consumer goods (a pack of pasta, a toothpaste and a basic t-shirt) was investigated under the following three conditions: the post-promotional phase of a "buy one, get one free" offer, the post-promotional phase of an economically equivalent 50% discount and a situation in which no price promotion was applied at all. For the consumer non-durable pasta, the results suggested that consumers’ value perceptions would be significantly influenced by whether or not a price promotion was previously applied and if so, which one. Furthermore, for the noodles, the findings seemed to corroborate the hypothesis that consumers' willingness to pay is highest in the absence of any previous promotion. Surprisingly, no significant difference was found between the post-promotion phase of the discount offer and the post-promotion phase of the BOGOF offer for any of the three products. All in all, this research provides some meaningful insights on the potential long-term impacts of price promotions on consumers’ value perceptions and willingness to pay. Moreover, our findings could be of particular relevance for managerial decisions regarding the marketing of non-durables in the grocery sector
