The little stickers shoppers drop off at their local supermarket have had a tangible benefit at schools such as St Joseph's.
The Murray Bridge school took a delivery of programmable bee robots and kits for drawing circuit boards using a special pen on Wednesday, to the delight of students.
Principal Adrian Brown also welcomed the delivery, which was accompanied by several trays of fresh fruit.
"Anything we can possibly get for the educational needs of these kids, we take with open arms," he said.
"At Catholic schools we have to do a lot of our own work.
"The kids appreciate it."
The delivery was a product of Woolworths' Earn and Learn program, which will deliver 300,000 educational resources to schools around Australia.
Shoppers decide which school to support by dropping stickers, gained in exchange for purchases, in bins outside their local store.
Murray Bridge Green Woolworths manager Wade Kluske said it was great to be involved in the community.
"It's not just about toys, it's about promoting healthy eating, helping educate the next generation to make healthy life choices," he said.
