Buy four get 30% off: how consumers respond to missing a quantity discount

Abstract

Purpose

This paper aims to examine how consumers evaluate and respond after failing to receive the promotional price for a quantity discount because the minimum purchase requirement (MinPR) is out of reach. Although quantity discounts are effective in terms of increasing sales volume, the outcome of using them is not always positive.

Design/methodology/approach

Two 2 × 2 experiments are carried out to test the research hypotheses in the context of apparel shopping.

Findings

The results of Experiment 1 demonstrate that offering quantity discounts with a high MinPR (e.g. “4 for 30 per cent off”) can result in greater willingness to buy (WTB) a single product at the full price than offering promotions with a low MinPR (e.g. “2 for 30 per cent off”) in the wake of a missed quantity discount. In other words, the purchase quantity has a positive effect on the consumers’ WTB even when they are not able to take advantage of the discount. However, this relationship weakens when the selection of discounted items is limited (i.e. the scope of the promotion is narrow). The results of Experiment 2 reveal that when the missed quantity discount is based on dollars rather than on the number of pieces (e.g. “Buy $100, get 30 per cent off” vs “Buy four pieces, get 30 per cent off”), the effect of purchase quantity on WTB is enhanced. Finally, perceived closeness of purchase outcome to the MinPR mediates the effect of purchase quantity on WTB.

Research limitations/implications

To maximize internal validity, hypothetical scenarios were used as stimuli rather than an actual consumption experience, and the setting involved only a single product category (clothing). Future work including other types of merchandise and a more natural setting is needed to generalize our findings.

Practical implications

The purchase quantity or MinPR serves as a reference point that influences consumers’ purchase decisions, even those who do not buy enough to qualify for the price reduction. Our findings suggest that retailers should specify a relatively high MinPR for quantity discounts. In addition, proper selection of the promotional scope and discount base will significantly improve consumers’ behavioral reactions when they are not able to take advantage of a quantity discount.

Originality/value

The primary contribution of this article to the marketing literature is that it provides empirical results that shed some light on the situational influences that missing a quantity discount has on the consumer’s WTB a single product at the regular price, and what the mechanisms for the purchase quantity effect might be.
