I agree that the troops don't make but a few cents on a box of cookies, but what I think is worse is the way some schools handle the sales.
I received an email from one of the students with a pdf catalog and her number (so she would get credit). I ordered, paid shipping, and the items were delivered to the house. The items were very high priced, high shipping and poor quality. I'll do it again because I know the girl, but I really appreciate when the parents cover the sales!
