A new BBC investigation has found that Tesco was overcharging customers on multi-buy offers at two-thirds of its stores.
The investigation, which will air on tonight’s episode of Inside Out, has prompted the supermarket giant to check the prices of all items in every one of its 3500-plus UK stores to ensure customers were not being short-changed on promotions.
An undercover reporter for Inside Out was charged more than expected in 33 out of 50 stores visited because promotions marked on the shelves were out of date and no longer valid at the tills.
In some cases, the reporter found that multi-buy deals were still being advertised even though they had expired months ago.
A Tesco spokeswoman said: “We take great care to deliver clear and accurate price labels for our customers so they can make informed decisions on the products they buy.
“We are disappointed that errors occurred and will be working with the stores involved to reinforce our responsibilities to our customers.”
In the episode, Chartered Trading Standards Institute’s Martin Fisher said errors like this could break the law according The Consumer Protection from Unfair Trading Regulations 2008.
Inside Out airs on BBC at 7.30pm tonight.
