Lower prices also eliminate the expense of frequent sales promotions and sales are more predictable. Cross docking gives the individual managers more control at the store level. A company owned transportation system also assists Wal-Mart in shipping goods from warehouse to store in less than 48 hours. This allows Wal-Mart to replenish the shelves 4 times faster than its competition. Wal-Mart owns the largest and most sophisticated computer system in the private sector.
