Wait...are you really spending more just to earn a sticker?
Spoiler alert: it’s not you, it’s a brilliant marketing strategy.

In a world saturated with digital loyalty points and complicated app rewards, something simple is making a powerful comeback in South African retail. Across the country, from SPAR and Pick n Pay to Food Lover's Market, a small, sticky piece of paper is proving to be a highly effective tool for brands. We’re talking about sticker campaigns.

For every R100 you spend, you get a sticker. Collect enough to fill a card, and you can buy premium products like Nutrifresh glass containers, Curver kitchenware, or even German Silit pans at a massive discount. These aren't just discounts; they're the core of a genius loyalty loop designed to keep you coming back for more.

So, why are these low-tech campaigns so successful in a high-tech world? It all comes down to a few brilliant psychological principles.

1. The Psychological Game: How Stickers Hook Your Brain

This isn't about saving money; it's about a well-timed dose of dopamine. Sticker campaigns are engineered to tap into our most basic human desires, turning a simple shopping trip into a rewarding quest.

‍

It's All About the Goal-Gradient Effect

The core of a sticker campaign's success lies in the goal-gradient effect: the principle that people are more motivated to accelerate their efforts as they get closer to a goal.(Kivetz, 2006) When a customer has a partially filled sticker card, they are psychologically driven to make more frequent or larger purchases to complete it and earn the reward. (Renascence, 2025)The visual progress of the stickers on the card serves as a powerful motivator.

Building Habits Through Positive Reinforcement

Every time a customer receives a sticker, they get a small, immediate reward. This act of positive reinforcement encourages the customer to repeat the behavior, shopping at that specific store (Renascence, 2024). Over time, this consistent reinforcement can lead to habit formation, making the store their default choice for groceries. This process is rooted in our brain's reward system, which releases dopamine in response to positive stimuli, strengthening the link between the action - shopping at the store - and the reward - the sticker. (Smitizsky, Liu, Gneezy, 2021)

The Emotional Investment of the Endowment Effect

Once a customer has collected a few stickers, they begin to feel a sense of ownership over the reward they are working towards. This is known as the endowment effect.(MOO Print, 2025) The value of those stickers increases in their mind, making them less likely to abandon the campaign and switch to a competitor, even if they offer a better immediate deal. You’ve invested time and effort, and you're now psychologically committed.

Tapping into Nostalgia and the Joy of Collecting

In a digital-first world, the physical act of peeling and placing a sticker is a powerful sensory experience ( Chen, Huang, Zhang, 2020) . It’s a tactile act that makes the reward feel more real and more valuable. (InstantPrint, 2019) For many South Africans, it can trigger a nostalgic, childlike feeling of being rewarded for good behavior, like a gold star in school. This simple act creates an emotional connection that a digital points app simply can’t replicate.

2. The South African Sticker Phenomenon

South African retailers have perfected this strategy, creating campaigns that have become ingrained in our shopping culture. Here's how a few of them work.

The "Discount vs. Free" Strategy: A Lesson in Value

The genius of these campaigns lies in their tiered reward structure. It’s not just about a single goal; it’s about giving consumers a choice, which makes the campaign more inclusive and appealing.

• The "Free" Option: This is the ultimate motivator. The promise of a free high-quality item is a powerful psychological trigger. It taps into the human desire for a "win" and makes the effort of collecting every single sticker feel like a game with an irresistible prize. Customers are willing to spend more and shop more frequently to avoid paying anything for the aspirational product. This option is a powerful driver of extreme loyalty and higher overall spend.
• The "Discounted" Option: This offers an immediate and practical benefit, preventing consumer fatigue. Not everyone wants to commit to collecting dozens of stickers. By offering a significant discount after a smaller number of stickers, retailers make the reward more accessible. This lower barrier to entry ensures that even less frequent shoppers participate, driving up their average basket size and keeping them engaged. It's a transparent form of "deal loyalty" that builds trust by proving the value of the campaign early on. (BizCommunity, 2025)

In both cases, the retailer wins. They drive up sales and create repeat customers, while the cost of the "reward" is often a calculated part of the marketing budget, offset by the increased revenue. The sticker becomes a tangible proof of a genuine deal, building trust and strengthening the brand's reputation for offering value. (Shivkumar, 2025)

Aspirational Products, Tangible Rewards

• The Curver Freebie: Pick n Pay's campaign for Curver glass containers offers a powerful two-tier reward system. Customers receive a sticker for every R100 spent. They can collect a certain number of stickers (e.g., 25) to get the container at a reduced price, or collect even more stickers to get the item for FREE. This dual approach caters to different consumer mindsets.

• MasterChef & NutriFresh Collections: SPAR's campaigns for Nutrifresh containers and MasterChef knives follow a similar model. For the Nutrifresh campaign, a customer with 25 stickers can purchase a container for R59.99, but with more stickers (e.g., 45), the item is completely free. The MasterChef campaign offered up to a 70% discount on cutlery, turning everyday meal prep into a "MasterChef moment".

• Premium German Cookware: Food Lover's Market has run campaigns offering high-quality Silit cookware. Once customers collect the required stickers, they can purchase these premium German-made pans at a significant discount, with savings of up to 80%. The perceived value of getting a high-end, durable item for a fraction of the cost makes the effort incredibly worthwhile.

3. How Brands Benefit

Sticker campaigns are far more than a feel-good gimmick; they are a highly strategic and cost-effective marketing tool that delivers measurable results. From the retailer's perspective, these campaigns are a direct pipeline to increased sales, enhanced loyalty, and a powerful return on investment (ROI). Here's a breakdown of the core business benefits.

‍Driving Sales and Purchase Behaviour

The most immediate and tangible benefit is the impact on a customer’s shopping habits. These campaigns are meticulously designed to manipulate two key metrics: purchase frequency and basket size.

• Increased Purchase Frequency: The very nature of the sticker card compels customers to return. To complete the card and get their reward, they must make multiple trips. This turns a one-off visit into a series of repeat visits, directly boosting foot traffic and online orders.
• Higher Basket Sizes: By setting a minimum spend threshold, for example, R100 to earn one sticker, retailers nudge customers to "round up" their purchases. A customer with a R95 basket is psychologically incentivized to add a small item to reach the R100 mark, ensuring they don't miss out on their progress toward the reward. This seemingly small action has a significant cumulative effect on average transaction value.

Building Deep-Rooted Brand Loyalty

In an age of endless choice, winning customer loyalty is a brand's greatest asset. Sticker campaigns are exceptionally good at converting a transactional relationship into an emotional one.

• Creating Emotional Loyalty: Unlike a cold, impersonal loyalty card that just tracks points, the sticker card creates a sense of shared journey and effort. By rewarding loyal customers with valuable, high-quality items, the retailer fosters a feeling of being appreciated and valued. This emotional connection is far stronger than mere transactional loyalty and is what keeps customers from switching to a competitor.
• Building Brand Habit: Over time, the consistent positive reinforcement of earning stickers turns shopping at that particular store into an ingrained habit. The customer begins to default to that retailer automatically, a powerful form of brand loyalty that requires little to no conscious decision-making.

Strategic Partnerships and High ROI

The benefits extend beyond the retailer to their brand partners, all while maintaining a remarkably low cost for the campaign itself.

• Partner Brand Exposure and Cross-Promotion: These campaigns are often a strategic collaboration with a specific brand (e.g., NutriFresh, Curver, or MasterChef). The campaign gives the partner brand massive, co-branded visibility, introducing their products to a large and engaged customer base. It's a win-win: the retailer offers an attractive reward, and the supplier gains significant sales and brand exposure, sharing the cost and amplifying the reach of the promotion.
• High ROI and Cost-Effectiveness: Compared to expensive traditional advertising like TV spots or large-scale print ads, the cost of producing stickers and a limited number of discounted items is minimal. The campaign's success is driven by organic word-of-mouth marketing and customer-led engagement, making it one of the most cost-effective ways to drive sales lifts and repeat purchases. It's an investment that pays for itself through increased revenue and solidified brand loyalty.

4. What Brands Can Take Away

The success of these South African campaigns offers a powerful blueprint for effective marketing. Here's how any brand, regardless of industry, can apply these principles to build a more engaged and loyal customer base.

• Make Progress Visible: It’s not enough to simply have a loyalty program; you must make the customer’s progress tangible and easy to track. Whether it’s with physical stickers, digital badges on an app, or a simple progress bar, this visual feedback is a powerful motivator. By showing customers exactly how close they are to their reward, you tap into the psychological principle of the Goal-Gradient Effect, encouraging them to increase their frequency of interaction or purchase size to reach the finish line. This transparency builds trust and keeps the customer psychologically invested in the outcome.

• Balance Short-Term Wins with Long-Term Loyalty: A successful loyalty program requires a two-pronged approach. The immediate reinforcement , the dopamine hit of receiving a sticker or an instant discount, keeps the customer engaged in the short term. This small, consistent reward strengthens the brand-customer bond with every transaction. However, the larger, delayed reward, the free or heavily discounted aspirational product, is what drives long-term loyalty and repeat business. This strategic balance ensures that customers are rewarded for both their small, frequent actions and their overall commitment to the brand.
• Use Sensory Marketing: In a world of digital overload, a physical, tactile experience stands out. The act of collecting and placing a sticker is a form of sensory marketing that creates an emotional anchor that digital-only programs can't replicate. The feeling of peeling a sticker and the visual satisfaction of a filled-up card make the loyalty program feel real and more valuable. Brands can replicate this by incorporating tangible elements into their customer experiences, whether it's through a physical loyalty card, a unique unboxing experience, or a memorable in-store activation.

• Reward Effort, Not Just Spend: Customers love to earn rewards; it feels more valuable when they’ve "worked" for it. Simply giving a reward based on a high spend threshold can feel impersonal. A campaign that requires effort, like collecting multiple stickers over time, makes the final reward feel earned. This taps into the psychological principle that things we work for are more valuable to us. By framing the program as a fun challenge or a rewarding journey, brands can deepen customer engagement and make the final reward a true celebration of their loyalty.
• Collaborate Strategically: Partnering with complementary brands is a powerful way to amplify reach and share costs. By collaborating with a high-end kitchenware brand like Silit or a household staple like Curver, retailers can offer an aspirational reward that they might not otherwise carry. This co-branded approach is a win-win: the retailer drives sales and customer loyalty, while the partner brand gains massive visibility and a new customer base. This strategy also deepens community connection by bringing together two trusted brands that align with the customer’s lifestyle and values.

5. Closing Thoughts: The Timeless Power of Simplicity

In a world where marketing is increasingly complex, digital, and data-heavy, the humble sticker campaign serves as a powerful reminder of what truly works. It's a low-tech solution that leverages high-level psychology to achieve remarkable results. These campaigns don't just sell products; they build emotional connections, foster a sense of community, and create a powerful feeling of accomplishment. They turn a routine chore, grocery shopping, into a rewarding game, one that customers are eager to play and win. The success of SPAR, Pick n Pay, and Food Lover's Market's campaigns proves that sometimes, the most effective way to build loyalty is not through a complicated app, but with a simple, tangible reward that speaks directly to our human desire for progress and value.
