More and more people have sought food and furniture from the Salvation Army in Murray Bridge this year.
Captain Tim Watson said staff and volunteers at the organisation's community service were booked out most days, meeting with people who needed help with their finances or basic needs.
They helped about 18 people per week.
"We try never to turn people away, but when our appointments are booked out, we can only do a certain number," Mr Watson said.
"We do give food away to people who can't get an appointment."
The Salvos will call for donations for their annual Red Shield Appeal, the main fundraiser for the service, next week.
But to make that happen, they need volunteers to collect the money.
A stall will be set up at the Murray Bridge Marketplace for two weeks from next Monday, and Mr Watson hoped to find about 50 people who could man it for two hours each.
