Last year while waiting in line at the Post Office, I was harrassed 3 times by the same girl trying to sell me cookies. Myself and the others waiting in line were disgusted by it. The girls mother didn't seem to care that her daughter was so pushy.
Here is a very good article that was in the Philadelphia Inquirer about the Girl Scouts prices on cookies.
