I only spent $50, which was the application fee. I already have a graduate degree; therefore, I didn't need to re-take the GREs and the admissions committee already had my transcripts on file from the last time I graduated from their school. Painless!
I got into GMU's MPA program and this is my 1st semester in the program. The only reason why I'm getting a MPA is to try to get a federal government job (i.e., job security).
Why are you getting a MPA (or MPP)?
