Dear friend,
I am sorry to say that we have no in stock now, can you change another style? otherwise, we only can refund you.

Hi friend, I am sorry it is out of stock in our warehouse. May I change another type for you? If you mind, I will refund you.

Is unfair to my warehouse not to have on-hand merchandise, asks you to trade a design, if you the original intention I do not refund money for you
