It's sort of like buying a car. No kidding. Basically, call them and state your case. Your daughter would like to go there, but it is going to cost more, and money is tight. We did that with one of our kids (at another school), and it worked. After telling the story to other people, I found it's not uncommon, although not well-known. I know it seems a bit unseemly at first thought, but it is done, and they are used to it. The system is broken, but that's another story.
