Holiday shoppers who plan to mail their gifts have until Dec. 21 to mail First-Class and Priority Mail items in time for Christmas. For last-minute shoppers, Dec. 23 is the last day to ship Express Mail packages.

Atlanta district manager Kate F. Wiley said the U.S. Postal Service is up to the challenge.

“Americans can count on the Postal Service to deliver their holiday gifts in time for Christmas as we have for the past 234 years,” she said. For those who don’t want to wait in line at the post office, Wiley recommends automated postal centers, or APCs, or shipping online.

Automated postal centers are standalone mailing kiosks available in post office lobbies, including at 520 W. Ponce de Leon Ave. in Decatur; 4325 First Ave. in Tucker; 1785 E. Park Place Blvd., Suite 201, in Stone Mountain; and 1705 Highway 138 S.E. in Conyers. Customers can use the APC to get stamps; weigh packages; and calculate postage for Express, Priority, First-Class and Parcel Post.

“APCs make visiting a post office easier,” Wiley said. “It’s one more way we’re trying to save customers time waiting in line and offering another alternative to meet their mailing needs.”

Customers can skip the trip to the post office completely by visiting usps.com, where they can print shipping labels, pay for postage and order free shipping supplies, including Priority Mail flat-rate boxes.
