Postal Service’s Busiest Day

If you want your greeting card to arrive in time for Christmas, today is the last call.

The United States Postal Service said today would be its busiest day of the year, with about 800 million letters and packages expected to enter the system. This marks a 40 percent increase in average daily mail volume of 559 million pieces of mail.

“If customers get their cards and packages to us by Tuesday, Dec. 21, we’ll get them delivered by Christmas,” postmaster general Patrick R. Donahoe said in a statement.

The 2010 holiday season follows the USPS’ worst fiscal year ever, with a net loss of $8.5 billion. For details of the fiscal year ending Sept. 30, click here.
