When Do Christmas Cards, Letters, And Packages Need To Be Sent?
With my parents in Pennsylvania, my sister in Singapore, and my in-laws near Raleigh, I rely on the post office to get Christmas cards and packages where they need to be every holiday season. Since Charlotte is very much a city of transplants, I know I’m not alone.
The U.S. Postal Service expects customer traffic to increase beginning December 10th. The week of December 17-23 is predicted to be the busiest mailing, shipping and delivery period with nearly three billion pieces of First-Class Mail, including Christmas cards, being processed and delivered. If you don’t want to stand in long lines, send your stuff as soon as possible.
