It's a busy day at post offices across the country.
Today is expected to be the busiest mailing day of the year for the United States Postal Service as folks get out those last minute holiday cards, letters and packages.
Officials say Thursday is the last recommended day to send mail expected to arrive before Christmas Eve. After that, USPS recommends the 2-day Priority Mail service or overnight Express Mail.
If you haven't had the opportunity to mail out your items, and would choose to opt out of waiting in line, an expedited process is available by using the self-service kiosks.
The kiosks are available 24 hours a day.
The USPS could see an estimated 658 million items passing through today alone. that's an increase of about 130 million over the average daily volume of mail.
