It has been revealed that Tesco and Sainsburyâs customers are paying more than Waitrose shoppers if they are not using a Nectar or Clubcard.
Which? compared a list of 245 branded items, such as Heinz, Nescafé, and Mr Kipling in February, finding that it was, on average, most expensive for customers at Sainsburyâs and Tesco who were not using the loyalty schemes.
The watchdog acknowledged that most shoppers are part of a membership scheme, but said some may be unwilling to sign up to loyalty cards for reasons such as data privacy, while others have no choice because of eligibility criteria.
Tesco customers who are under 18 can not sign up to a Clubcard, although the supermarket has announced it will review this before the end of the year. Honestly I’ve been using lynx for year’s but in tesco £5.90 for a can of antiperspirant is absolutely shocking…. Think it’s time to use another brand… Deals are only on a short while and I’m fed up with it… Nearly 20 year’s using your products #expensive

Which? said the figures showed the âdramatic price gulfâ created by loyalty pricing.
Meanwhile, Which? found customers who used a Nectar card at Sainsburyâs could expect to pay only 3% more than Asda at £848.56 for the entire list of items.
Which? retail editor Reena Sewraz said: âOur analysis reveals a shocking truth and shows the impact loyalty schemes have had on grocery pricing.
âBranded favourites can actually be cheaper at Waitrose than at the UKâs biggest supermarkets for shoppers who donât use a loyalty card â something that would have seemed unthinkable until a few years ago.
âIf youâve got your heart set on specific brands, your best bet is to shop around, keep a close eye on the unit price, and stock up whenever you see a good deal â otherwise, youâre likely to end up paying way over the odds.
âWhile loyalty cards definitely offer some savings, if you donât use one youâre better off heading to Asda, where the pricing is usually cheaper on a range of branded goods.â

A Sainsburyâs spokesman said: âWe have invested over £1 billion in recent years to help keep prices low and we know more customers are choosing to do their shop at Sainsburyâs.
âWe are committed to helping customers access great quality at lower prices and remain focused on offering outstanding value across thousands of products through our Aldi price match scheme, Nectar prices, Your Nectar Prices and our own-brand value lines.â
A spokesman for Tesco said: âItâs no secret that Tesco Clubcard unlocks exceptional savings for the 24 million UK households who have one.
âMore than 80% of our sales are made with a Clubcard â but itâs just one of the ways our customers get great value.
âThough everyday low prices we keep prices consistently low on thousands of branded products, and our Aldi price match ensures shoppers can be confident theyâre getting competitive prices.â
