If you've bought something in the sale don't expect them to actually have it in stock. I made an order on the 29th Nov and have now been told on the 8th Dec they don't have it in stock. This was a Christmas present.. so if you don't have the stock then don't allow it to be ordered! This has happened numerous times. Asos is good for many things but don't trust they have the stock to fulfil orders.
