If-then promise

The pattern

This commercial ad is filed under If-then promise.

Define

A conditional contract: if you do this, you get that. The sentence can be tested against the reader's own case.

Mechanism

Specificity does the persuading. The if names the action. The then names the outcome. Hedging kills it.

Verdict

We can name both the action and the result without adjectives

Why it works

The 2+1 FREE badge, with a curved arrow looping from the 1 down to FREE, states the whole deal as arithmetic a child could read, and the bottom line spells it out for the parent: Buy 2 Kids Books & Get the 3rd FREE. Three real covers, 101 Early Learning, a sudoku book of over 1,000 puzzles and 505 Activities for Kids, run from preschool tracing to puzzle books, so a parent can picture a set of three before reading the date.

The big idea

For International Children's Book Day, kids' activity books come in threes: buy two and the third is free.

The offer

Buy 2 children's books and get the 3rd free, for International Children's Book Day. Valid until 11 April 2026, terms apply, on jarir.com.
