Dear Dr. or Prof. XXXX (family name of the Editor or Editor-in-Chief who issued the decision letter),
Re: Ms# XXXX (number of the manuscript if any) – XXXX (title of the article)
I am very pleased that our paper has been accepted for publication in XXX (name of the journal).
We notice that there is a charge for the publication of the manuscript (or for printing the color figures, or whatever you are charged). The publication fees (or costs for printing the color figures, or whatever you are charged) appear too expensive for me at the moment. Although this project was supported by a grant from ****, but the total amount of the grant was RMBXXXX (about $XXXX). With this amount, we could just mange to conduct and complete our experiments, and thus we do not have enough funding to pay for the publication fees (or for printing the color figures, or whatever you are charged).
Therefore, I am writing you to explore the possibility that the publication fees (or for printing thecolor figures, or whatever you are charged) could be reduced or even waived. However, if youhave a difficulty to offer us such a concession, we will make our every effort to meet the requirements for the publication including payment of the publication fees (or for printing the color figures, or whatever you are charged) since the publication of this paper in your journal is very important for us.
Thank very much for your consideration, and look forward to hearing from you soon.
With kind regards,
XXXX (name of the corresponding author)
