I'll go with these numbers are from the days when they didn't have Wal-Mart data, and so we allowed a bigger difference between ours and theirs. Even at this point, you have to expect differences between both sources because neither has 100% tracking of the market.
Although it is strange that they are all under, and by a fairly significant number. Maybe those NPD numbers include Canada, but I doubt that.
