Up to my ears in money!!!

So because I am PTO co-president, I have the "honor" to count and make sense of all the orders through the fundraiser. I swear, people don't know how to add. How is it that several people can turn in orders of $80- to $200 dollars and not send in all the money? Now I get to take time out of an already busy schedule to call these people and tell them they need to bring in more money. I hate making these calls. Oh well. Hopefully we made enough money to cover our activities and some teacher enrichment for the next year. We need to find a better fundraiser out there - this one was the worst I've ever experienced..
