Dear

It has been so long since we have had the opportunity to

be of service to you, that I have begun to wonder if

perhaps, we have offended you in some way in the past.

If this is the case, I would greatly appreciate knowing

what happened.  In fact, if you have any grievance with

our firm, I wish that you would call so that we might

discuss the problem.

We have introduced many innovations into our product line

since the last order you placed with our firm, and if the

reason we haven't heard from you has nothing to do with a

complaint, we would appreciate having the opportunity  to

show you these innovations.

In either case, it would be wonderful to hear from you.
