Also something about NPD then simulates a Wal Mart store through this method. Wal Mart also used to be a NPD client so they have historical data.
Pretty sure Wal Mart is the biggest electronics retailer as well, ahead of Best Buy. |
Yeah, i think you understimate how hard tracking like that can be... it's really hard statistically.
