They have been shipping from those warehouses for years. It is called drop-shipping. They do not own those particular warehouses. They list the items for sale and whether it is a manufacturers warehouse or a large distributor, when they makde a sale on Amazon(no longer selling on Amazon) or eBay they would notify the warehouse and they would ship it. Essentially what fulfillment through Amazon is as well. I do think they are trying to set up their own warehouses though to be on shipping side of the equation.
