Just a note to let you know that my book order was received and I was very pleased with both the merchandise and the well-packaged and quick delivery of it. It was a pleasure doing business with you, and hopefully, I will be back again soon!
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.
