Let me take a moment to let you know how pleased I am not only with your timeliness and help, but also your honesty and commitment to your customers. As an instructor at Duquesne University, I am always telling my students about responsibility and, lately, some of the book dealers have given me unnecessary difficulties... I am very pleased with the service I received from your company and will inform my fellow faculty members that they can look forward to professional service from your book shop. Again many thanks and I look forward to future dealings with your company.
Many thanks for your prompt reply informing me that the book is now set aside for the library. It's great that you are willing and able to send an invoice with the book -- it makes life a little easier when you work for a very large institution! Thanks again.
