You can’t discount your way into someone’s head (No matter how good the cake)!
Sale now on. Prices slashed. Summer sale. And the dreaded Black Friday promotions!
We get it. The temptation for promotions is like trying not to eat that last piece of Victoria sponge. You know you don’t want to. You know you shouldn’t, but the little voice of impulse just says ‘go on then!’.
Now swap the sponge for stock that’s not quite shifted. Black Friday’s coming up and everyone around you is always on sale. You know you don’t want to. You know it’s bad for you. There’s that little voice again: ‘go on then!’ And you hit sale anyway.
Of course, eating cake and brand promotions are two different scenarios, but the one thing they have in common is: you know it’s bad. You know you don’t want to, but you do it anyway. It’s bad for you, and the truth is it’s bad for brand.
Don’t believe us?
At the IPA Effectiveness Conference in October 2026, Les Binet and Kantar’s Dom Boyd presented a case against the industry’s promotion addiction. The title slide alone read: ‘The price promotions habit destroys profits. So why keep doing them?’
They’d surveyed the people who sign off on promotions. And like that last slice of sponge, they know it’s bad for them.
Four in five agree many of the shoppers buying on deal would have bought anyway. That’s a discount handed to someone already reaching for their wallet.
Three in four agree repeated promotions make shoppers more price sensitive. So every sale makes the next one harder to say no to.
Yet the second most common reason for their last promotion was clearing stock that hadn’t shifted. 17%.
Just like that last slice of sponge, knowing it’s bad hasn’t stopped anyone. Because while you might shift some stock, the shoppers you’ve discounted don’t come for the brand. They come for the low price, and the low price is what they’ll come back for.
So what does this mean for the brands in the promotion mix?
Binet and Boyd’s advice is to promote selectively, not reflexively.
Keep promotions when they recruit genuinely new buyers, generate full-price repeat, expand into new occasions, or reinforce what makes the brand worth paying for.
Stop when they subsidise people who were already buying, cannibalise your own portfolio, pull tomorrow’s sales into today, or divert the budget that should be building brand.
So when the temptation to hit promotion comes around again, and it will, just like that last slice of Victoria sponge, ask yourself: are they buying the brand or just buying the bargain? Because the shopper who only shows up when the price drops isn’t a customer. They’re a habit you’re paying for. And habits, unlike brands, are easy to forget.”
