Shoppers are being charged the wrong amount at the tills by supermarkets.

Research from Brighton and Hove City Council’s Trading Standards team shows up to half of goods bought from big stores are incorrectly priced.

Every supermarket visited by council officials charged the wrong price for a group of items picked off the shelves.

The results have prompted the local authority to issue warnings to the unnamed chains to price their products properly.

The research, which has been put together over the last few months, looked at supermarkets who failed to match shelf prices with the amount charged at the till.

It showed the worst performing store had errors on 48% of 150 items checked by the trading standards officials.

This included a combination of undercharging, overcharging or incorrect multi-offers.
