Researchers at The Hong Kong Polytechnic University, University of British Columbia, and Singapore Management University conducted a set of studies about these promotion types in order to better understand consumer reasoning about them.
For the consumer, capped promotions are economically superior to threshold promotions until their spending reaches the promotional trigger value, after which the two promotion types are economically equivalent. The researchers say we might be surprised their study participants preferred threshold promotions over capped promotions for relatively small-dollar discount offers.
The explanation is twofold. First, the high percentage number in most capped promotions—such as 50%—leads consumers to perceive more promotional benefits than the actual small monetary benefit they receive—such as $5. Second, a low spending threshold—such as “on orders of $10 or more”—leads consumers to perceive a small discount—such as $5—as relatively large by comparison.
When trigger values clearly exceed the shopper’s usual spending for the item type, consumer reasoning changes: Shoppers then tend to see capped promotions as better than threshold promotions, as they objectively are. Underpinning this consumer reasoning across item type, price promotion type, amount of discount, and whether the discount is stated as money or percentage is the degree to which the shopper considers a transaction to be equitable and profitable for all parties.
The full set of study outcomes resulted in the researchers advising that if quickly gaining market share is your top objective, offer a threshold promotion with a low trigger value or a capped promotion with a high trigger value.
Further, in my email exchange with Shangwen Yi, the lead researcher, he wrote, “For capped promotions, a smaller percentage can be better received by consumers than a larger one. We found that 20% appears to be the sweet spot, but this result is context-specific. It’s based on a food ordering setting with typical spending patterns and a $3 cap. If the cap were increased to $10, for example, I’d expect the optimal percentage to rise to a larger value, such as 30% or 40%. Set the percentage around the ratio of the cap amount to consumers’ usual spending in that shopping context.”
