Barclays Bank in Buckingham is collecting food for the new Buckingham food bank, which launches in January.
Waitrose has kindly loaned a supermarket trolley, which is now in the window of the bank, on Market Hill, where people can donate items for local people in need until Friday, December 27.
Manager Sarah Hammond said the initiative is part of a Barclays community week.
She said: “We had a discussion within the team what we would like to do, and we decided the food bank would really help the people of Buckingham and the villages.”
Anyone can donate food at the branch. Food must be non-perishable, such as cans, jars and dry food, including boxes of cereal, tea and coffee.
Household items such as soap, shampoo, toothpaste, toilet rolls and nappies are also welcome, but not clothing or toys.
The food bank will be run by the mission and outreach team from Buckingham Parish Church, which already supplies emergency food parcels to people referred by agencies including Citizens Advice and doctors’ surgeries.
Until now, the team have had to shop for each food parcel as it it needed. But from January, thanks to an anonymous donor, the church will have premises where it can store food until it is needed.
Food buyer Amy Urquhart-Winter, said: “It will make it a lot easier for the people who buy, and quicker as well.
“Now we’re going to be able to bank food. At the moment, people say: ‘Can I donate?’ and we have to say ‘No.’”
And she added: “It’s just for local people. People here might seem quite affluent but it’s a big spectrum.”
Mrs Hammond said: “It can affect anybody, can’t it?
“You don’t know from one day to the next when you might need some help.”
