No help to you now but, I NEVER buy goods on line unless they state that the item is in stock. Even then, I check that the item is still in stock when I've placed the order. The reason for this is that on one occasion an article was claimed to be in stock when it wasn't. The vendors said that two people had placed an order at the same moment and their computer hadn't updated when I placed my order.
They must have thought I fell off a Christmas tree.
