Monday is likely to be the busiest mailing day of the year for the U.S. Postal Service and private shippers will also be busy moving millions of parcels.
There is still time to mail, but Christmas is drawing close. Ralph Petty, spokesman for the Postal Service in Sacramento, suggests people use priority mail to make sure packages get to their destination.
Priority mail gets to its destination in two or three days.
Express mail is even faster: overnight delivery to most areas in the country.
Sacramento-area postal workers will process about 2.4 million cards, letters and packages on Monday.
Normally, workers would handle 700,000 in a day.
FedEx expects to handle a record-breaking 280 million packages worldwide between Thanksgiving and Christmas, an increase of 13 percent from last year.
