Promotional discounts have a design flaw: they require nothing. The customer finds the code in their inbox, applies it at checkout (if they remember), and feels nothing except mild satisfaction at having done something obvious. The brand gives away margin and gets back a transaction with no attachment to it. Any competitor who spots the deal can match it before lunch.
The campaigns in this guide make the discount contingent. A chase through live sports photography. A shaking phone. A licence plate number entered on a website. A pair of shoes worn that must be worn to leave the shop. In every case, the mechanic that delivers the discount is also the thing that makes it worth having. You don't receive it. You earn it.
Here are five ways from the Commerce Engine to make that happen:
- The Chase
- Performance
- The Good Act
- Endurance
- Commitment
1. The Chase
Hide the discount inside something moving, live, or scarce — and make finding it the point.
Coupon Rain — Mercado Livre, GUT São Paulo, 2024
At the final of a major Brazilian football championship, Mercado Livre replaced traditional confetti with 50 different printed coupon codes. The trophy lift — the image guaranteed to flood every sports outlet, social feed, and newspaper front page — carried live discount codes embedded in the paper falling around it. Because 50 different codes were distributed across the confetti shower, different deals appeared in different photographs, driving fans to hunt across sports portals, social shares, and the official champions poster to find the best ones. The media ecosystem became the game map. 54,000 coupons were redeemed in four days. 847 million earned impressions. $3.8 million USD in extra sales — from confetti.
Cetrogar's Size of Your Envy (Ogilvy Argentina, 2026) asked Argentinians to WhatsApp a photo of a neighbour's TV box ahead of the World Cup. An AI tool read the box dimensions and replied with a personalised discount on a larger Quantic model. The trigger — neighbour envy — was already in the culture. The campaign gave it a destination. Volaris hid discount codes on aircraft wings (W1ng Cod3s, Havas HOY Mexico, 2024). Passengers who spotted the codes mid-flight, photographed them, and shared them online received valid vouchers. No campaign instructions — just curiosity and a phone camera. The plane was the creative. The passengers were the media.
