Tesco are making a change at their self-service checkouts from today.
As part of a charitable cause, shoppers will be asked if they would like to round up their total to the nearest pound before paying. The changes will be in place from September 12 until October 2.
It comes as Tesco plans to use the extra money to support an in-store fundraising campaign for three of the UK's leading health charities. According to the supermarket giant, the cash will go directly to Cancer Research UK, the British Heart Foundation, and Diabetes UK.
