Sure, but the vast, vast majority of their freight is Asia -> US. I work in the shipping/logistics industry and I assure you, Somalian piracy is not a threat to Wal-Mart's supply chain. It's barely a blip on their radar. If one container ship were hit and a few of their containers were on board it would not hurt them financially, they have cargo insurance anyway. Storms at sea are a much bigger risk factor, containers fall off of cargo ships in rough seas surprisingly frequently, and voyages often get delayed by a few days due to weather. Water damage due to holes in the shipping containers is also very common. And delays at the port and rail hubs due to congestion. These factors are all much bigger risks to Wal-Mart (or any major importer) than piracy is. It's kinda like worrying about carjackings when an accidental collision is probably thousands of times more likely to kill you.
