Stoney at the McDonald’s drive-through

An amber bottle, a plain burger box and a pair of sneakers.

Stoney, the South African ginger beer, teamed up with McDonald’s for a drive-through campaign that ran from 24 September to 1 October 2022. The job was simple: get people to buy, make the entry obvious, and put a prize on the table that people actually wanted.

The mechanic

Buy the Blitzbokke Boerie Meal in the McDonald’s app. Photograph the till slip. Send it on WhatsApp. A valid slip was one entry into a draw for one of 250 pairs of exclusive Stoney Bathu sneakers. People were already in the drive-through, already holding a slip, and already on WhatsApp, so the promotion never asked them to learn a new place to enter.

What Smartslip.ai did

  • Checked the slips, so only a real purchase of the meal counted.
  • Kept the door on WhatsApp, which is why participation stayed high.
  • Collected consumer data alongside the entries, so Stoney could see who had taken part and shape the next push.

The journey

  • Awareness in the McDonald’s app and in the restaurant.
  • Purchase of the Blitzbokke Boerie Meal.
  • A photo of the till slip, sent on WhatsApp.
  • A valid slip goes into the draw for the sneakers.

What Stoney got back

  • Sales. The prize sat behind a purchase, so the competition itself moved product.
  • Engagement. The sneakers and the short entry kept people interested.
  • Loyalty. A reward people wanted is a reason to come back.
  • Data for the next campaign, not only a winner’s name.

What the reporting showed

The live view covered total entries, how many people that was, how many slips each person sent, and how the entries fell across the week. Those are the counts SmartCheck is there to produce. The campaign increased sales, lifted engagement, and left Stoney with a clearer picture of the people who bought.
