πŸ’Ž On how shifting a brand’s comparison set can radically change willingness to pay (Tesco, PG Tips and Twining’s)

In one study I told participants that a 250g box of PG Tips cost Β£2.29, while the same weight of Tesco own label tea cost Β£1. When questioned about the price, 31% of the respondents rated PG Tips as good value.

I then asked another group the same question but with one tweak. Rather than compare PG Tips to own label it was contrasted with Twining’s, priced at Β£3.49. In this scenario, the number who thought PG Tips represented good value jumped to 65%.

Brands can apply price relativity in two broad ways. First, don’t accept your comparison set as fixed. Do everything you can to change the field of reference shoppers have to one that is even more profitable to you.

πŸ’Ž On obsessing over easily quantified data often having damaging results (the invention of the Tesco “Free From” range)

The obsession with easily quantified date crowds out the need for discretion and judgement.

Two examples illustrate the resulting issues. First is the experience of Terry Leahy who, when he was head of marketing at Tesco, analysed the performance of their gluten-free products. The sales data hinted it was an under-performing section – those that bought gluten-free goods only spent a few pounds on these items each shopping trip. A naive interpretation suggested de-listing them to free up valuable shelf space.

However, sceptical of the number, Leahy interviewed gluten-free shoppers and discovered that their choice of supermarket was determined by the availability of those products. They didn’t want to make multiple shopping trips, so the visited whoever had the specialist goods. After all, every shop had milk and eggs but only sone stocked gluten-free goods. Leahy used this insight to launch Tesco’s hugely successful “Free From” range long before the competition.
