How three words boosted sales by 50% | Nudge Newsletter


"Pre Season SALE"

Read online


Marketing scientists Eric Anderson and Duncan Simester¹ had a simple question:

Does the word “sale” boost sales — even if the price doesn’t change?

To find out, they teamed up with a clothing catalogue company.

Anderson and Simester sent out two versions of the catalogue to 50,000 people.

  • In one, some dresses were labelled “Pre-Season SALE.”
  • In the other, those same-priced dresses had no sale tag.

The result?

Simply adding the word “sale” boosted purchases by over 50%.

This is the anchoring effect. People’s decisions are influenced by reference points, even if they’re irrelevant.

3 more anchoring examples

We're significantly influenced by anchors.

Reading "Pre-Season SALE" encourages us to buy, even without a discount.

But that's not all anchoring does:

1️⃣ A London property firm struggled to persuade new callers to list their homes.

Adding² the anchor “Let me connect you to Peter, our head of sales with 20 years’ experience” to the receptionist welcome script boosted appointments by 20% and contracts by 15%.

2️⃣ Say you need to run 10 km.

Which feels easier? 2 km then 8 km, or 8 km then 2 km?

Research³ says to anchor with the longer distance first.

3️⃣ Tourists spend less⁴ in a country where the nominal value of the currency is high.

You'll overspend when the foreign currency is smaller (e.g., 0.8 EUR = 1 GBP) but underspend when it’s larger (e.g., 150 JPY = 1 GBP).

A massive thank you to today's sponsors.

The Contrast Effect Read online Rosser Reeves, an American ad executive from the 1950s, was eating lunch in Central Park. He and his colleague saw a man begging for money. It was late afternoon, but the beggar hadn't made much money. Reeves told his colleague: “I bet I can dramatically increase the amount of money that guy is raising simply by adding four words to his sign." The colleague agreed, and Reeves introduced himself to the homeless man. He explained that he knew something about...

Expense Boosts Value Read online This quote summarises one of the most overlooked marketing lessons. Rory Sutherland in Alchemy¹ This idea (that expense boosts value) is known as costly signalling. I did a silly, and simple, experiment² to prove it. I showed 200 random Brits an ad for my podcast. 50% saw only the ad. 50% saw the ad superimposed onto a billboard. The billboard signaled expense, and it made Brits 61% more likely to listen. But advertisers can push this further. Rather than just...
