Dear Fellow classmates，
our class is to hold a charity sale to raise money for those children who are in need of help.I'm calling on all students to take part in it. In this charity sale,old books,clothes and other things will be sold at a low price.We will appreciate it if you could either donate some old things or choose and buy goods you need in this charity sale.The money collected will be used to help those kids who are eager to learn knowledge but can not afford their education.
It's our duty to provide as much help as we can in the hour of need.Thanks for your attention to the email.
Yours Sincerely,
