ELI5: How are small donations, like 10 cents, able to buy a meal for charity, where regular people can't get a stick of gum for that much?

For one, they buy in bulk. You get much cheaper prices when you order for something like a kitchen than you do at your local grocery store.

They also tend to buy cheap things. Beans, rice, that kind of stuff.
