Sorry for the "newbie" question.
As you can tell by post count, I am still new at this. (But as you can tell by my name, I am not new at gaming).
Nevertheless, I remember once hearing that NPD measures about half of US retailers and then makes necessary calculations to come up with full sales figures. I also remember hearing that one of those that it did NOT measure was Wal-Mart.
Is this true? Also, if this is true, could non-inclusion of certain chains/stores be biasing the results.
What made me think of this was some of the great variations in software counts between VGChartz and NPD.
Thanks in advance
