Auto Zone Ordeal

Most likely when you ordered them they come from the manufacture and ship to the store ( generally 2 days ) This is called VDP. Maybe the vendor had a problem with their inventory that delayed the shipment. And of course Autozone can't control that. I doubt very much that those would come in on their weekly truck shipment from their distribution center. Now if there was a delay in shipping the store can see it if they look it up and it will also give them a estimated ship date.
