McDonald's sells bags of ice cubes that weigh about 10 pounds. Cost of a bag of ice ranges from $0.99 to $1.49 per bag. McDonald's ice is more stable and clear than ice from other grocery stores. McDonald's cleans and sanitizes its ice buckets and ice scoops every day. Similarly, the ice machine in any McDonald's store is cleaned monthly.
McDonald's does not sell crushed ice. If you visit your local McDonald's, ask for a bag of ice. As a whole, though, be sure to check before you go to your nearest McDonald's to see if they have ice.
