When you cannot give full attention to the request immediately, at
least write the inquirer and tell how you will reply fully in a day
or so or whenever you can. If you can truthfully say so, tell him
that you have just what he wants and ask him to wait to get your
full information before placing his order. In this way you may hold
the matter open.
