As presents start to pile up under the tree, packages and letters are piling up high at the post office.
It's organized chaos inside the U.S. Post Office this time of year. Letter after letter and package after package, run over, under and through a sea of employees trying to sort it all.
Managers tell us, this time of year the post office never closes down.
"Twenty-four seven, every holiday," said Mark Stickrod, Senior Manager.
A total of 4.6 million pieces of mail are sorted a day and starting next week that volume will bump up to 6 million.
"When you have a package mail. Don't wait two or three days, just mail it," said Stickrod.
With a late Thanksgiving, this Christmas deadline is creeping up fast. Post Office managers said the busiest day will be December 16th.
Before slapping a stamp on a package and stuffing it in the mail, remember to pick a strong sturdy box and tape it up tight. Because by the time it gets to it's destination if will have twisted, tumbled and turned twelve ways to Sunday.
The final days to get packages in the mail are December 20th for first class mail, December 21st for priority mail, and December 23rd for priority mail express.
