Van is right. With more than 4 or 5 receipts floating around, I would be thinking that they are adding them up and using the total. Like 5 receipts of $100 =$500 paid in daycare fees. That's why you write copy on the 2nd one. My advice, STOP. Say "no more." After that many, losing them, not your problem. And BTW, they haven't filed their taxes yet? They're in for some penalties. Also not your problem.
