USPS projects they'll deliver 15-billion pieces of mail by the end of the holiday season.
San Angelo's postmaster says he is ready.
"The whole week is going to be the busiest week of the year," San Angelo Postmaster Jose Chappa said. "We expect a crowd. It's nothing new for us. We expect it and we're ready for it."
While the amount of letters is expected to decline this year from last year, package deliveries are projected to increase 12-percent.
"In San Angelo, through the month of November, we have had a 3-percent increase on our packages," Chappa said, adding that increase will continue through December.
Lines at San Angelo post office's were long, but moving steady on Monday. To ensure "organized chaos," the post office says nearly 75-million customers will ship online this year. Others will use a convenient tool now offered in many post office lobbies.
"Four years ago, the postal service came up with the automated postal center," Chappa said. "That's a great tool for customers to use. It's available 24 hours a day, seven days a week."
Customers can buy stamps and ship packages from these service centers.
To make sure packages are delivered by Christmas, packages must be shipped on December 21, or through priority mail express up until December 23.
