Promotional pricing is often the only tool used to generate volume. Ask any salesperson ‘Why’ and they will say ‘because it works’. Go next door and ask a marketer, and their response is more likely to be something like: ‘to encourage non-users to try the product, and if they like it, to come back, become loyal customers’

Therein lies the paradox. The well intentioned promotion of a brand results in killing it.

By promotional pricing the product down, you reward current users who would have bought at full price, while not being effective at persuading potentially new users to try for any reason other than price.

The power of habit is huge in routine purchases, like the ones we make every week in the supermarket. A regular consumer is not necessarily loyal to a particular brand, they are more unthinking, more habitual than most marketers will concede, especially to themselves. If a choice is to be made to change brands, that decision takes up cognitive capacity better dedicated elsewhere, and involves risk, which we are programmed by evolution to avoid.

To change habits, we must change behaviour, an extremely challenging thing to do.

Psychologists have found over and over, the best way to change habits is to change little things, one at a time, progressively leading to the changed behaviour that in its turn becomes a habit. Each stage takes 3 or 4 times to become sufficiently entrenched to start to take on the characteristics of a habit.

Back to our supermarket.

Price promotions follow each other on a weekly basis. No brand is given the time to establish its routine purchase as a new behaviour, as there is a price promotion of an alternative brand every week, often several at the same time.

The net result is that for every product on shelf, the discounted price becomes the ‘real’ price, which becomes less and less relevant as consumers are trained by the retailers to think that the discount price is the real price for the products and the categories.

That, in a nutshell, is why we are seeing less and less brands on the supermarket shelves, and as a direct result, less and less innovation, as suppliers have little chance of recouping development costs in such an environment.
