The Christmas season is a busy time of year especially for the post office. Despite the anthrax scares recently the post office is expecting this holiday season to be one of the busiest. With the increased volume of packages and letters, WHIZ talked to a postal worker about when to send your items so they get to your loved ones on time. They suggest letters should be sent 7 to 10 days before Christmas. Mondays are the busiest days for mail. December 19th is the busiest delivery day, and December 17th is the busiest mailing day.
