If you want your mail to jingle all the way to its recipient before Christmas, there are some dates to remember, says McMinnville postermaster Brent Nunley.“For domestic mail to get there before Christmas, standard post is Dec. 15. First-class mail and priority mail is Dec. 20, and you can wait up until Dec. 23 for priority mail express,” said Nunley. “Priority mail express is our fastest service.”The need for customers to avoid procrastination is the abundance of mail projected during the holiday season.
