A recent investigation by consumer watchdog Which? has unveiled that customers at Tesco and Sainsbury’s are paying significantly more for popular branded groceries compared to their Waitrose counterparts, provided they are not enrolled in loyalty schemes. The analysis, which examined 245 branded products including well-known names like Heinz and Nescafé, highlights the growing disparity in pricing tactics among the UK’s major supermarkets.

Price Comparison Highlights

The study assessed the costs of various items, revealing that non-members of Tesco’s Clubcard and Sainsbury’s Nectar scheme are at a distinct disadvantage. For those without loyalty cards, Sainsbury’s emerged as the most expensive option, with an average total of £942.66 for the selected items. This price is a staggering 14% higher than Asda, which offered the same goods for £823.58. Tesco followed closely behind, charging £916.56, or 11% more than Asda’s prices.

Interestingly, the research excluded discount retailers like Aldi and Lidl due to their limited range of branded products, which could have skewed results. Nevertheless, the findings underscore that even Waitrose, often perceived as a premium retailer, offered a more competitive average price of £899.05 for the same selection of goods.

Loyalty Schemes: A Mixed Blessing

Which? noted that while many consumers are part of loyalty programmes, a portion of shoppers may hesitate to join due to concerns about data privacy or ineligibility. For instance, individuals under 18 cannot sign up for a Tesco Clubcard, although the supermarket has announced plans to reassess this policy by year-end.

The pricing discrepancies become even more pronounced when examining specific products. For instance, Amoy Straight To Wok Noodles were available for £1.25 at both Waitrose and Morrisons, but non-card holders at Tesco and Sainsbury’s faced an average price of £2.15—a significant 72% markup.

Additionally, branded items like Carex Hand Wash and Kellogg’s Crunchy Nut Cornflakes were found to be cheaper for Clubcard users at Tesco compared to Waitrose. This stark contrast illustrates the substantial impact that loyalty schemes can have on grocery bills, making it crucial for shoppers to consider their membership status when planning purchases.

The Implications for Consumers

The research has sparked discussions about the effectiveness of loyalty pricing strategies. Which? retail editor Reena Sewraz remarked, “Our analysis reveals a shocking truth and shows the impact loyalty schemes have had on grocery pricing. Branded favourites can actually be cheaper at Waitrose than at the UK’s biggest supermarkets for shoppers who don’t use a loyalty card—something that would have seemed unthinkable until a few years ago.”

Both Tesco and Sainsbury’s defended their pricing structures. A spokesperson for Sainsbury’s highlighted the supermarket’s investment of over £1 billion in recent years to maintain competitive prices, while Tesco emphasised that more than 80% of their sales occur through Clubcard transactions, reinforcing the importance of these loyalty programmes for consumer savings.

Why it Matters

This analysis sheds light on a critical aspect of modern grocery shopping: the role of loyalty schemes in determining prices. For consumers who prefer not to engage with these systems, alternatives like Asda may provide better value for branded goods. As supermarkets continue to refine their pricing strategies, the findings serve as a reminder for shoppers to remain vigilant about where they spend their money, particularly in an era where every penny counts.
