The Potters Bar branch of the supermarket launched a competition in which customers had the chance to take part in a lucky dip to find a golden version of Tesco’s blue voting token.
The winning token was then used to vote for one of three selected charities to receive the money.
The winner selected Carers in Hertfordshire, a charity that supports and advocates for unpaid carers.
The cash injection will fund triage and activity days for young carers and their families in the Potters Bar area.
Tasneem Choucair, community fundraising officer at Carers in Hertfordshire, said: “We are grateful to Tesco and their customers for this generous donation.
“This support will help us give young carers, who look after someone close to them who is ill, disabled, or elderly, opportunities to have fun, improve their confidence and wellbeing, and develop their skills away from their caring roles.”
Virginia, community champion at Potters Bar Superstore, said: “Tesco Potters Bar is delighted to be participating in Golden Grants.
“Our customers were really keen to get involved and the recipient truly deserves this support.
“We are delighted to be able to help them.”
