Tesco has been accused of 'breaking the law' with its Clubcard price promotions.
Consumer group Which? has reported the UK's biggest supermarket chain to the Competition and Markets Authority (CMA) amid concerns that it does not provide detailed pricing information on its loyalty card offers.
The complaint is around Tesco's unit pricing, the small print on shelf price tags which give the price of the product per 100g or 100ml to enable shoppers to compare the value for money between different-sized products and brands. Which? said the lack of unit pricing could be a “misleading practice” under consumer protection regulations as it had not clearly explained the unit price of deals for its Clubcard holders.
