Time is running out for people who need to send gifts to loved ones ahead of Christmas this year. FedEx says December 15th is the last day to get ground packages out for Christmas delivery and the U.S. Postal Service suggests getting boxes and cards in the mail no later than the 16th. UPS has said customers should consult their website for an updated estimate on shipping time. Many retailers are planning to offer free shipping and guaranteed delivery by Christmas Eve on orders placed next Thursday, December 14th.
