In a fiercely competitive retail landscape, understanding the nuances of shopper behaviour is paramount for sustained growth. Our client, a mid-sized South African grocery retailer, recognised the need to delve deeper into their customers' in-store journeys. Facing stagnant sales and a declining average basket size in key categories, they partnered with us to uncover actionable insights that would revitalise their market position.
The Business Problem: Stagnant Baskets and Eroding Share
The client operated across multiple provinces, including Gauteng, the Western Cape, and KwaZulu-Natal, with a diverse portfolio of store formats ranging from compact urban express centres to larger suburban supermarkets. Despite a strong brand presence, internal analysis revealed a worrying trend: average basket size in core categories such as dairy, packaged groceries, and impulse snacks was steadily declining. This indicated a potential disconnect between their merchandising strategies and actual shopper needs, leading to missed sales opportunities and an erosion of market share in a highly saturated sector.
The challenge was clear: how could they optimise their in-store environment and promotional strategies to encourage shoppers to add more items to their baskets and increase overall spend? Without a clear understanding of shopper motivations and friction points, any intervention would be speculative and potentially ineffective.
The Research Design: A Multi-Faceted Approach
To comprehensively analyse shopper behaviour, we designed a robust, multi-method research programme across 20 of the client's strategically selected stores. This sample represented a cross-section of their store formats and geographic locations (Gauteng, Western Cape, KZN), ensuring regional and format-specific insights could be captured.
Methodology:
- In-store Observation: Our trained researchers meticulously observed over 1,500 shopper journeys. This involved tracking paths to purchase, dwell times in specific aisles, interactions with promotional displays, and instances of product selection or abandonment. This qualitative data provided invaluable insights into the physical flow and 'feel' of the shopping experience.
- Shopper Intercepts: We conducted over 750 short, structured interviews with shoppers at the point of sale or upon exit. These intercepts aimed to uncover the 'why' behind observed behaviours, exploring purchase drivers, unmet needs, perceptions of value, and reasons for selecting or overlooking specific products. Crucially, we ensured a balanced representation across various Living Standards Measure (LSM) bands to capture socio-economic influences on shopping behaviour.
This combined approach allowed us to move beyond mere sales data, providing a rich, contextual understanding of the shopper's mindset and actions within the retail environment.
The Insight: Shopper Journey Diverged by Format and LSM
The research revealed a critical insight: the shopper journey was far from monolithic. It differed significantly based on both the store format and the shopper's LSM band, directly impacting purchase behaviour and basket size.
- Store Format Discrepancies:
- Express Stores: Shoppers in urban express centres were highly mission-driven, prioritising speed and convenience. They navigated directly to essential items or 'grab-and-go' solutions, often bypassing categories perceived as requiring more browsing time. Impulse purchases were minimal unless strategically placed for immediate visibility.
- Standard/Super Stores: In larger suburban formats, shoppers were more open to browsing and comparison. However, certain categories, such as snacks and specific dairy items, suffered from poor visibility and illogical placement, often located far from complementary products (e.g., biscuits for coffee, or cheese for crackers). This led to missed cross-category purchase opportunities.
- LSM Band Behaviour:
- Lower LSM: These shoppers were highly price-sensitive and value-driven, meticulously comparing unit prices and responding strongly to clear, visible multi-buy offers on staple goods. Their focus was on bulk value and essential items for household provisioning.
- Mid-High LSM: While still value-conscious, these shoppers prioritised convenience, quality, and variety. They were more receptive to premium product offerings, lifestyle-oriented messaging, and solutions that saved them time (e.g., pre-cut vegetables, meal kits).
The existing planogramming and promotional strategies were largely uniform, failing to capitalise on these distinct shopper behaviours.
The Activation: Tailored Planogramming and Promotional Strategy
Armed with these granular insights, we collaborated with the client to implement a targeted activation strategy:
- Category Re-planogramming:
- Express Stores: Redesigned layouts to create 'mission zones' (e.g., "Lunch on the Go" combining sandwiches, drinks, and fruit) and optimised checkout areas for high-impulse, single-serve items.
- Standard/Super Stores: Implemented significant category shifts. Dairy was repositioned closer to breakfast cereals, and the snacks aisle was completely overhauled, grouping complementary items (e.g., crisps with dips, biscuits with coffee) to encourage linked purchases.
- Optimised Promotional Strategy:
- LSM-Specific Offers: Promotions were tailored. Lower LSM shoppers received clear, prominent multi-buy offers on bulk essentials, while mid-high LSM shoppers saw offers on premium products or convenient meal solutions.
- Enhanced In-store Communication: Signage was redesigned to be clearer, highlighting value propositions for lower LSM and lifestyle benefits for mid-high LSM shoppers. Colour-coded price tags were introduced to simplify comparison.
- Digital Integration: Geo-targeted digital coupons and loyalty programme offers were deployed, aligning with the specific needs and behaviours observed in different store formats and LSM profiles.
The Outcome: Significant Growth in Basket Size and Market Share
Within nine months of implementing the new strategies, the client experienced a remarkable turnaround:
- Average Basket Size: Increased by an impressive 6% across all store formats.
- Market Share: Grew by 3 percentage points in the core categories that were the focus of the intervention, signalling a strong competitive advantage.
- Category-Specific Uplifts: Dairy sales saw an 8% increase, while the redesigned snacks aisle reported a 12% uplift. Customer feedback indicated a more intuitive and satisfying shopping experience.
This case study powerfully demonstrates how deep-dive shopper research, when translated into precise, data-driven activations, can fundamentally transform retail performance and drive sustainable growth.
