Er... considering that NPD and their internal trackers are also just polling retailers... I fail to see the difference.

Outside of sample size anyway.

NPD also includes consumer side tracking (ie: polling) in their methodology.  In fact, that's specifically how they cover Wal-mart and Sam's Club.

Hell, NPD had a registered polling base of 1.8m.  They tout it on their site even.

True.  By "just"I didn't meant that was all they were doing, I meant that it was the exact same thing.  In otherwords that THEY are polling as well.
