You will only be able to order merchandise that is instock. If your size is not available, then you will not be able to select that size. However if we find an item is in stock but not suitable for sale, for reasons beyond our control, we will remove it from your bag and ship the order excluding that item and refund the value of the removed item. Should you have an item in your bag that was in stock but subsequently is out of stock, you will be prompted to remove the out of stock items before proceeding to check out.
