A price displayed on a supermarket shelf or promotional poster is one of the main factors shoppers use when deciding whether to buy a product.

But recent consumer complaints documented by the Competition Authority of Kenya (CAK) show that the amount displayed to a shopper and the amount eventually charged at the checkout have not always matched.

The issue is more than an inconvenience. For consumers shopping on tight budgets, a difference of even a few hundred shillings can affect what they are able to take home.

Recent cases documented by the CAK involve complaints against major retailers including Carrefour, Naivas and Quickmart, as well as concerns about product labelling and the way promotions are presented to consumers. The cases provide an important reminder that shoppers should check both the advertised price and their final receipt.

What CAK found about supermarket prices

One of the clearest examples involved Carrefour and a five-kilogramme packet of Dawaat rice.

According to the CAK’s annual report, a consumer complained after seeing the rice advertised as being on promotion but discovering that the price charged at the till was different.

The authority intervened, the customer was refunded and a warning was issued to Carrefour before the matter was closed.

The case is significant because it demonstrates the practical problem created when promotional information displayed to shoppers does not correspond with the price programmed into a retailer’s checkout system.

A similar complaint was recorded against Naivas.

A consumer complained that an alcoholic beverage advertised on social media at Sh899 was sold to him for Sh1,120. The case illustrates another potential source of confusion for shoppers: the price communicated through a retailer’s digital channels may not necessarily correspond with the amount charged at the physical outlet.

Quickmart also appears in the CAK’s records.

In a case involving the retailer’s Nyalenda outlet, consumer JME Simekha alleged that he was charged more than the advertised offer price when refilling cooking gas. The CAK annual report records the matter as ongoing.

These cases should not automatically be interpreted as evidence that retailers deliberately overcharge customers. They are complaints and regulatory investigations, and each case has its own circumstances and outcome.

That distinction is important when assessing allegations against individual businesses.

Why shelf-price errors matter to consumers

The problem with an incorrect price is not simply that a shopper may lose a few shillings.

Consumers make purchasing decisions based on the information available to them. A shopper who sees rice advertised at a discounted price may decide to buy it because it fits within their budget. If the checkout price is higher, the shopper is effectively making a purchasing decision using information that did not match the final transaction.

This becomes even more significant during large shopping trips.

A difference of Sh50 or Sh100 on one product may appear insignificant. But when several products carry different prices at the shelf, promotional display, mobile application or checkout, the total difference can become substantial.

For households carefully managing weekly or monthly budgets, accurate pricing is therefore a consumer-protection issue rather than merely a customer-service complaint.

What Kenyan law says about misleading consumers

The CAK’s consumer-protection mandate is anchored in the Competition Act.

Sections 55 to 70 of the Act give the authority powers relating to consumer protection, including matters involving false or misleading representations and other forms of conduct that can affect consumers.

This means retailers are expected to provide consumers with accurate information about the goods and services they sell.

The principle extends beyond price tags.

Consumers also need reliable information about what they are buying, including product descriptions, expiry dates, ingredients, quantities and other information required under applicable standards.

The CAK’s supermarket investigations therefore looked beyond checkout prices.

The authority also examined product labelling and whether consumers were being provided with essential information about products.

That wider approach matters because a consumer cannot make a fully informed purchasing decision if important information is missing from the product packaging.

The hidden problem with supermarket promotions

Supermarket promotions are designed to influence purchasing decisions.

“Was Sh1,200, now Sh899”, “buy one get one free” and other discount messages create a sense of value and urgency. Consumers may choose a particular retailer or product because they believe they are getting a better deal.

That is why the accuracy of promotional information matters.

The CAK has previously identified dual pricing and other consumer-protection concerns within Kenya’s retail sector. Its earlier inquiry highlighted issues including expired or unsafe goods, product labelling, warranties, handling of complaints and return policies.

The regulator’s findings suggest that pricing transparency cannot be separated from the broader question of whether consumers are receiving sufficient and accurate information before making purchases.

What shoppers should do at the supermarket

The CAK cases also offer a practical lesson for consumers.

Shoppers should develop the habit of checking the price displayed on the shelf against the price appearing on the receipt.

This is particularly important when buying promotional products.

Before leaving the checkout area, consumers can:

Check the receipt against the prices displayed on the shelves.
Pay particular attention to discounted or promotional items.
Take a photograph of a promotional price where there is a significant discrepancy.
Keep the receipt if the amount charged differs from the advertised price.
Ask the supermarket’s customer-service desk to explain or correct the discrepancy.
Record the branch, date and product involved when making a complaint.
Preserve screenshots when a promotional price appeared on a retailer’s website or social-media page.

Keeping evidence is especially useful because it allows a consumer to demonstrate exactly what price was advertised and what amount was eventually charged.

Are pricing discrepancies always deliberate?

Not necessarily.

Retailers operate large stores containing thousands of products, and prices can change frequently. Promotional campaigns may also run for limited periods, meaning shelf labels, electronic systems and digital platforms have to be updated.

One supermarket executive quoted in reporting on the CAK findings attributed some discrepancies to human error and the manual updating of shelf prices.

That explanation is relevant, but it does not remove the consumer’s concern.

From a shopper’s perspective, the important question is not necessarily why the error happened. It is whether the customer was charged the price they were led to expect.

Retailers therefore have an interest in ensuring that their pricing systems, promotional material and shelf labels remain synchronised.

CAK also found product-labelling concerns

The investigation was not limited to prices.

The CAK found that sugar sold under Shivling Supermarket lacked important information, including the date of manufacture, expiry date and batch numbers required under relevant standards. The regulator extended the investigation involving the retailer beyond June 2025.

Product labelling is particularly important because it allows consumers to establish what they are buying and whether a product is suitable for consumption.

The issue also connects the supermarket investigation with earlier enforcement work by the CAK involving bread manufacturers.

In that earlier case, the authority found problems involving manufacturing dates and other information on bread packaging. Manufacturers were directed to provide clearer information, including ingredients, net weight and manufacturing dates, and to use “Best Before” rather than “Sell By” when indicating expiry information.

The pattern demonstrates that consumer protection in Kenya goes beyond the amount printed on a price tag.

It also concerns the quality and completeness of the information available to shoppers.

What the supermarket probe means for consumers

The most important lesson from the CAK findings is that consumers should not assume every price displayed in a supermarket will automatically correspond with the amount on the receipt.

That does not mean shoppers should distrust every retailer or assume every discrepancy is deliberate.

Instead, consumers should become more deliberate about checking promotional prices, receipts and product information.

For retailers, the cases demonstrate the importance of maintaining accurate pricing systems and resolving complaints quickly when mistakes occur.

For the regulator, the investigations show why consumer complaints remain an important source of information about problems in the retail market.

The CAK’s intervention in individual complaints has also demonstrated that a consumer who identifies a discrepancy does not necessarily have to absorb the loss.

In the Carrefour case, for example, the shopper was refunded after the complaint was investigated.

The bigger issue: trust in Kenya’s retail sector

Supermarkets compete heavily on price, convenience and promotions. Consumers therefore rely heavily on the information retailers provide when deciding where and what to buy.

That makes pricing accuracy a matter of trust.

If a shopper repeatedly encounters differences between shelf prices and checkout prices, confidence in promotional campaigns can decline. Conversely, transparent pricing and quick resolution of mistakes can strengthen the relationship between retailers and their customers.

The CAK’s findings should therefore not be viewed only as a list of complaints against individual supermarkets.

They provide a broader picture of why accurate prices, clear promotions, proper product labelling and effective complaint-handling systems matter in Kenya’s retail economy.

For consumers, the simplest takeaway is equally important: check the price, check the receipt and keep evidence when the two do not match.

Where a consumer believes a retailer has engaged in conduct that may breach consumer-protection requirements, the matter can be raised with the Competition Authority of Kenya for consideration.

The regulator’s supermarket findings reinforce a basic principle of retail trade: consumers should be able to make purchasing decisions using information that is clear, accurate and not misleading.
