Why “Buy One Get One Free” Deals Are So Effective

Supermarkets frequently employ “buy one get one free” (BOGO) offers,and for good reason. These stack discounts aren’t simply a gesture of goodwill; they tap directly into the way our brains are wired to perceive value and reward, driving increased purchasing behaviour. Neuromarketing experts and consumer behavior analysis reveal the powerful psychological mechanisms at play.

the Neurological Basis of Stack Discounts

martin de Munnik, a leading neuromarketing expert, explains that our brains constantly evaluate the balance between what we gain and what we expend. “our brain weighs up what something yields and what it costs,” he states. When confronted with a BOGO deal, this calculation is heavily skewed towards the perceived benefit. “If you see a 1+1 free discount, our benefit mechanism is triggered.”

This response isn’t a rational one; it’s deeply emotional. De Munnik emphasizes that we make many purchasing decisions based on feeling,not logic. “If we see the price of one product, and we see that we get one for free, that advantage mechanism works even better, because you are rewarded for the ‘smart’ deal you do.” The feeling of securing a bargain activates our brain’s reward system, creating a positive association with the purchase.

The Effectiveness of Frequent,Smaller Discounts

Interestingly,De Munnik suggests that a more effective strategy for retailers might be to offer smaller,more frequent discounts throughout the store. “Smaller discounts throughout the store. Then our reward system works every time.” This approach would consistently stimulate the reward system, potentially leading to sustained engagement and increased overall spending.

Supermarket Strategy: Driven by Results

According to industry analyst, Sloot, supermarkets utilize stack discounts not out of generosity, but because they demonstrably increase sales. “Not because they like it, but because they see that it is effective because people buy more.” The impact of discount booklets and promotional materials is significant.

Sloot highlights the extent to which consumers actively seek out these deals. “45 percent of households look at the brochures and decide partly on the basis of these brochures where and what they buy.And that percentage has also grown.” This demonstrates the powerful influence of perceived savings on consumer purchasing decisions and underlines why supermarkets continue to rely on these tactics.
