NPD doesn't track Wal Mart or did it change?

They don't get data from WalMart. They extrapolate to get their numbers (just like VGC does) since they do not have full market data (NPD has ~50% iirc).

You can add  5-10% to NPD numbers since then don't track every U.S. retailer and then don't track Wal-Mart at all which is THE biggest retailer in the U.S. lol!! NPD numbers are always undertracked.  VGC first adjusted numbers where pretty much accurate.
