Well, this is not a formal order but, I may place an order of 10 units for item A. Do you have 10 units in stock? How long will it take if you put it on backorder? I hope I can get orders.
I may order ten of A although I am still thinking about this and the previous one. Do you have ten of A in stock? About how many days will it take if you don't have enough on hand and order them? I hope you will be able to order them..
