Supermarkets still up to pricing tricksClaims of better value packs at Tesco and Asda

Supermarket shopping

Which? has found that Tesco and Asda have still been making claims of 'bigger pack, better value' that were not true.

The latest follow-up by Which?, on the back of our investigation into supermarket prices late last year, has revealed more instances of items sold at Tesco and Asda where larger or multi-pack versions are advertised as 'special' or 'mega' value, but in fact buying the individual or smaller equivalents is cheaper.

At Asda, we found a 56-pack of Finish All in 1 dishwasher tablets for a 'mega value' £13.58, but buying two 28-packs would have saved more than £1.50. Asda's website showed a 'better value' four pack of Princes tuna for £5.38, but if you'd bought four individual tins it would have cost just £4.

Find out how Finish tablets performed in our expert lab test of dishwasher tablets.

Tesco and Asda price 'errors'

Which? also found a 'special value' four pack of Green Giant sweetcorn niblets at Tesco was more expensive than four individual tins of the same item, as it was back in December when we reported the supermarket to trading standards officers.

Tesco and Asda have told Which? that the prices were errors and have since changed them, which is also what they told us last year. We will still highlight these latest instances to trading watchdogs.

Take a look at how Tesco and Asda fare against competitors such as Waitrose, Sainsbury's and Morrisons in our supermarket survey of more than 12,000 Which? members.
