First reserve your sno cone machine, then order your supplies. We recommend one order for every ten people. On average, each person will want two servings. For example, if you expect twenty children at a party, order two (approx. 40 servings). For larger events, you can begin to reduce the # of servings, because you may limit everyone to one. I know it sounds complicated... We'll be happy to help you estimate the amount of supplies you need. Call us if you have any questions. Supplies include: at least 3 flavors of syrup and cones. SORRY, WE DO NOT SUPPLY ICE.
