Pringles, Engen, Coca-Cola and a Jeep

A plain crisp tube, a simple can, a small toy car and a fuel pump.

From 1 May to 30 June 2024, Pringles, Engen and Coca-Cola offered a brand-new Jeep Renegade to people who bought their snacks and drinks at Engen Quickshops. The prize was the hook. The partnership was the engine.

How to enter

  • Start on WhatsApp and follow the prompts: date of birth, first name, surname, and an email if you want to leave one.
  • Consent to hear from Coca-Cola later is its own question, separate from sending the slip.
  • Buy a participating Pringles product and a participating Coca-Cola product at any Engen Quickshop.
  • Photograph the till slip so it shows the products, the date and the Quickshop, and send it on WhatsApp.
  • A shared slip, or a slip that has been altered, is out. The purchase has to fall inside the dates.

Why a promotion like this works

  • Footfall and basket. People come to a specific shop, and they buy two brands, not one. Volume and the average transaction both move.
  • WhatsApp. The entry lives in an app people already use, so more of them finish it and feel connected to the brand.
  • Data. The registration collects a name, an optional email and a separate marketing consent you can use on the next campaign.
  • The prize. A Jeep Renegade puts excitement and a bit of luxury next to a snack and a drink, and people remember who offered it.
  • The partnership. Pringles, Coca-Cola and Engen each bring a customer base. The exposure is shared, and so are the new buyers.

A simple door, a basket that has to contain both products, and a prize people will tell a friend about. That is how the three brands drove sales and left people with a reason to come back. How a second or altered photo is handled is in how duplicate and fraudulent till slips are stopped.
