Arundel Brownies and Rainbows went shopping to learn about meal planning and the cost of food.
The children from 1st Arundel visited Morrisons Littlehampton with leader Rachel Stanford.
She said: “The Rainbows had to think of a meal for £5 and the Brownies had to come up with a three-course meal for £5 in groups. Then they went shopping.
“All the food has gone in the food box for Littlehampton and District Foodbank.”
She thanked Alison Whitburn, the store’s community champion, for her support.
