Expecting to see that new tablet, game system or any other hot item this holiday season outside your door?

If it’s to ship by regular mail, you might get it a bit sooner than usual.

The U.S. Postal Service in Mississippi will deliver packages seven days a week in 21 cities through Christmas Day, starting the day after Thanksgiving, the service announced in a news release Monday.

“Every household in America relies on us to get their packages in home for the holidays, and we take great pride in taking on that responsibility,” Mississippi District Manager Elizabeth Johnson said in a statement. “We’re prepared to do whatever it takes to delivery for our customers.”

It includes packages bound for Vicksburg, as well as, in alphabetical order, Bay St. Louis, Biloxi, Brandon, Canton, Clinton, Corinth, Grenada, Gulfport, Hattiesburg, Jackson, Madison, Meridian, Natchez, Ocean Springs, Olive Branch, Oxford, Pascagoula, Pontotoc, Southaven and Tupelo.

Email and online shopping have prompted improvements to the postal service’s product line, which is expected to pump up package business in the mail this holiday season by 12 to 14 percent compared to last season.

Mailing and shipping deadlines for Christmas Day are as follows:

• Dec. 2 – First-Class Mail International/Priority Mail International

• Dec. 10 – Priority Mail Express International

• Dec. 15 – Standard Post

• Dec. 17 – Global Express Guaranteed, which involves additional days to clear customs

• Dec. 20 – First-Class Mail/Priority Mail (domestic)

• Dec. 23 – Priority Mail Express (domestic)

The postal service estimates about 75 million customers will purchase labels, boxes, postage and other services online this season via its Click-N-Ship option.
