Wal-Mart is incredibly stupid if they have not diversified their supply chain over the last two years. When I worked for the Global Sourcing department of Wally in Bentonville in 2003-2005 I kept asking what would happen if one missile flew over the Taiwan Strait.
I’m not sure they appreciated me asking that.
Wal-mart built a mini city to produce just in time production for every item containerized per store for shipment to keep the shelves full.
