The Psychology of the ‘Bargain’: Decoding High/Low Pricing
Have you ever felt the rush of grabbing a “half-price” electric toothbrush at Woolworths, only to realize a week later that the same deal has migrated to Coles? You aren’t imagining it. This is the “high/low” pricing strategy—a retail dance where the two biggest players in the Australian grocery market alternate discounts to create a perpetual sense of urgency.
At its core, this tactic relies on a psychological loophole: consumers generally have poor price memory. Instead of remembering the average cost of an item over six months, we react to the perceived value of the moment. When a product like an Oral-B iO3 toothbrush drops from $199 to $99.50, the brain registers a “win,” regardless of whether that price appears every second week.
Data from price-tracking tools like Guardian Australia’s analysis reveals that products—ranging from Coca-Cola to Fairy dishwasher tablets—often swap promotional status almost simultaneously. When one store hits the “low,” the other hits the “high,” ensuring that a discount is always available somewhere, but rarely everywhere at once.
The Future of Grocery Shopping: From Cycles to Algorithms
While the cyclical swap has been the gold standard for years, the retail landscape is shifting. We are moving away from simple calendar-based promotions toward a more complex, data-driven future.
AI Price Tracking: The Consumer’s New Weapon
The era of “guessing” if a price is actually low is ending. The rise of tools like CW Scanner allows shoppers to bypass supermarket marketing by scanning barcodes to see real-time price histories. As these tools integrate with AI, we can expect “smart shopping assistants” that notify users exactly when a product hits its absolute floor price.
This transparency puts immense pressure on retailers. When the “discount illusion” is stripped away by a smartphone app, supermarkets may be forced to move toward Everyday Low Pricing (EDLP) to maintain customer trust.
The Regulatory Shift: Ending the ‘Discount Illusion’
Regulatory bodies are no longer looking the other way. The ACCC has already scrutinized programs like Coles’ “Down Down,” focusing on whether these discounts are genuine or misleading.

Future trends suggest a tightening of “was/now” pricing laws. If a product is on sale for 26 weeks out of the year—as some ACCC reports suggest—regulators may eventually mandate that the “sale” price be listed as the “standard” price, effectively killing the high/low model.
Beyond the Store: The Role of the Supplier
It is a common misconception that supermarkets alone dictate these swings. Industry experts, including those from the Queensland University of Technology, note that suppliers (such as Arnott’s or Coca-Cola) often fund these promotional rotations.
Suppliers use this to maintain market leadership. By rotating the “deal” between Coles and Woolworths, they ensure their brand remains the most visible and “affordable” option across the entire retail landscape, regardless of which store the customer visits.
Dynamic Pricing: The Next Frontier
Looking ahead, the next evolution is dynamic pricing. Imagine digital shelf labels that change prices in real-time based on competitor moves, stock levels, or even the time of day. While this increases efficiency for the store, it could further erode price transparency for the shopper, making price-tracking apps more essential than ever.
How to Outsmart the Supermarket Cycle
To avoid falling for the “discount trap,” savvy shoppers should adopt a strategic approach to their weekly shop:
- Identify “Cycle Staples”: Track items like toilet paper, laundry detergent, and coffee. These are almost always subject to high/low pricing.
- Ignore the “Was” Price: Focus on the actual cost. If a product is $30 every other week, $30 is the real price, not the $76 listed on the tag.
- Use Comparison Tech: Leverage third-party apps to verify if a “half-price” deal is actually a rare occurrence or a weekly routine.
- Diversify Your Sources: Check if smaller independents or online wholesalers offer a stable price that beats the “high” phase of the supermarket cycle.
Frequently Asked Questions
What is high/low pricing?
It is a strategy where retailers alternate between charging a high standard price and a low promotional price, often in sync with their competitors to create a perception of frequent bargains.
Is high/low pricing illegal?
The strategy itself is generally legal, but it becomes a legal issue if the “original” price is fabricated or if the discounts are deemed misleading under consumer law.
Why do supermarkets do this instead of just lowering prices?
It triggers a psychological response in consumers, making them feel they have “won” a bargain, which encourages immediate purchase and increases foot traffic.
