Everything is relative. Where you live...where the artist lives...etc etc...
You can't expect the same rates in Des Moine, Iowa as you would in San Francisco.
That said, we don't discuss what you have paid/charged because of those factors, and because it may not always be the same for everyone else. Like @ian said, just be stoked with what you got, because money comes and goes, even for a relatively broke guy like myself.
