LIFESTYLE NEWS - With South African households counting every Rand, retailers competing for their money have a powerful advantage: they understand how consumers shop - often better than consumers understand themselves.
From the moment shoppers collect a trolley, they enter an environment carefully designed to influence where they walk, what they notice and how much they spend.
Store layouts, shelf positions, scents, sounds, pricing strategies and loyalty programmes can all play a role.
“We always think we are in full control of our free will when we walk through those doors with a trolley, but in reality, we are entering a highly calculated, scientific obstacle course,” says Prof Roland Goldberg, an expert in consumer behaviour, retail and place marketing at North-West University (NWU).
Why the milk is always at the back
Even the location of everyday essentials is carefully considered.
“Bread and milk are what we call destination products. People go to the store specifically to buy them. If they were placed at the entrance, customers could be in and out within two minutes, and the retailer would earn very little from that visit,” Goldberg says.
By placing these products towards the back, retailers encourage customers to pass rows of products that may tempt them to make additional purchases.
“The store layout can also leave shoppers slightly disorientated, encouraging them to abandon their clear purpose and begin browsing instead.”
Even the trolley itself can influence behaviour.
Trolleys have become considerably larger, Goldberg notes, and an almost empty trolley can create the feeling that shoppers have not bought enough.
Eye level is buy level
One of retail’s most established principles is simple: eye level is buy level.
Retailers use detailed visual maps called planograms to determine where products should appear on shelves. One of the most valuable positions is directly within an adult shopper’s line of sight, roughly 1.5 metres from the floor.
“People generally follow the path of least resistance and grab what is directly in front of them. Manufacturers are prepared to pay substantial slotting fees for that shelf space because they know how valuable it is,” Goldberg explains.
But shoppers prepared to look beyond the most convenient shelf may find better deals.
“Bargains, bulk packs and the store’s own cheaper house brands are often placed closer to ankle height, while premium niche products tend to sit above eye level. Looking beyond the most convenient shelf can save you money.”
When children enter the equation
The psychology changes when children enter the aisle.
Colourful cereals, sweets and other products likely to appeal to children are often positioned within their field of vision.
“Look at the cartoon characters on cereal boxes. Their eyes are often angled downwards so that they appear to make eye contact with a child walking beside the trolley or sitting inside it,” Goldberg says.
“That eye contact creates an emotional connection. The child begins pleading for the product, and the retailer knows that an exhausted parent shopping after work may eventually give in simply to keep the peace.”
The checkout temptation
By the time shoppers reach the till, they may have made hundreds of small purchasing decisions and be experiencing decision fatigue.
“At that point, the brain is looking for a quick reward. That is precisely why chocolates and sweets are placed there,” Goldberg says.
The checkout area can also function as a last-minute reminder zone, with batteries, razor blades, plasters, chewing gum and other small items positioned within easy reach.
“You are confined to a narrow space and cannot easily turn around or put something back,” he says.
The power of smell
Retailers also use the senses to shape the shopping experience.
Flowers near the entrance can create an impression of freshness, while the aroma of coffee or freshly baked bread can make shoppers feel comfortable - and hungry.
“Scent is powerful because it connects closely with emotion. A hungry customer is also likely to spend considerably more than someone who has eaten before shopping,” Goldberg says.
Even the floor can play a part
Some of the techniques are less obvious.
“Near expensive wines or beauty products, the floor tiles may become smaller. The trolley wheels click more quickly, the brain concludes that you are moving too fast, and you unconsciously slow down,” Goldberg explains.
“Very few shoppers realise that something as ordinary as a floor can influence how long they remain in an aisle.”
The longer shoppers stay in a store, the more opportunities there are for additional purchases.
Don’t be fooled by the discount
Pricing strategies provide another powerful psychological lever.
A retailer may display a high price, strike it through and replace it with a lower figure. The original price becomes an anchor, making the new price feel like a significant saving even when the product remains relatively expensive.
“The brain anchors itself to that first figure, so the new price feels like a victory, even if the product remains expensive,” Goldberg says.
Purchase limits can create a similar effect.
A sign stating “only four per customer” can trigger a sense of scarcity and encourage shoppers to buy more than they intended.
“The shopper may buy four items they did not need at all,” he says.
“The best defence is to ignore the excitement and compare the unit price - the price per 100 grams or per litre. That is the cold, hard mathematics behind the marketing.”
Your loyalty card knows what you buy
Loyalty programmes can provide valuable savings, particularly when household budgets are under pressure. But the benefit comes with an exchange: shoppers provide retailers with detailed information about their purchasing behaviour.
That data can reveal what customers buy, how frequently they shop and when they tend to make purchases.
“Use the discount to protect your wallet, but never allow the game or the chase for points to determine what enters your trolley,” Goldberg advises.
Shop with your brain, not your trolley
The best defence against supermarket psychology is awareness.
Goldberg’s advice is straightforward: eat before shopping, take a list and stick to it, compare unit prices and look beyond the products positioned at eye level.
“Every tactic works because it operates below our conscious awareness. The moment you can recognise it and name it, much of its power disappears.”
The next time you walk into a supermarket, then, remember: your trolley may have four wheels, but there is a lot of psychology helping to steer it.
Key shopping psychology tips:
- Eye level is buy level: Look up and down the shelves for cheaper house brands, bulk packs and genuine bargains.
- Cartoon characters are powerful: Cereal characters are often positioned to make eye contact with children, turning them into persuasive shopping influencers.
- Even the floor can influence you: Smaller tiles can make trolley wheels appear to move faster, subtly encouraging shoppers to slow down.
- Loyalty programmes come at a price: Discounts can save money, but shoppers also provide retailers with valuable data about their purchasing habits.
