“What happens when the warehouses run out of stuff...?”
Acquaintance that works in the Walmart distribution system at the warehouse to warehouse level said the containers from China have pretty much stopped.
That means that the regional distribution centers that distribute to stores will stop receiving shipments shortly if not already.
And that means that some stuff will be out of stock for realsies, soon.
How much food and perishables come from China?
A week ago, a female container truck drive at a ship yard had a video of how empty of containers and activity it was. No containers means no shipping to distribution centers which means shelves will get bare and stay bare.
