Dear complainers-
If you do not like VGChartz figures, I suggest you go to one of the other free webistes that track sales figures, and extrapolate for areas where they don't get direct numbers, and then work them all into numbers that are usually within miniscule percentages of the exact numbers that the manufacturers have. I'll wait here.
Sincerely,
Satisfied VGChartz User
P.S. I'm not waiting because you're not going to find another site like this.
