In this case, I would have her brainstorm some fund raising ideas. You can sometimes teach financial reality better by having them get involved in the process than just telling them NO. Girl Scouts have a lot of fundraisers and people like to give to Girl Scouts. I bet there will be a way for her to earn the money. It would be a shame for the 2 of you not to go. I would just tell her, Dad and I have gone through the budget and there we just don't have it, what are some ways you can think of to earn the money? Maybe call the troop leader and see if they have any funds available for this? I've been told that's where the cookie money goes. toward financing stuff like this.
