It's the biggest package delivery day of the year. The U.S. Postal Service, FedEx and UPS will drop off millions of packages on Thursday.
It's also a prime time for thieves looking to make a quick buck.
"We definitely don't want the Grinch to steal their Christmas, that's been our theme this year," said Sheree Robertson, an officer with the La Vergne Police Department.
Home security cameras in other cities have captured Christmas Grinches stealing decorations and even packages, right off the front porch.
Many houses in the Lake Forest Estates subdivision had packages in plain site, which, according to Robertson, is all the invitation a thief needs.
"If you are having packages delivered, maybe put a note on the door and ask them, if you're not home, to leave them at a neighbor's house or at their facility and you can come pick it up," Robertson added.
During the holiday season, La Vergne police increase patrols through the neighborhoods, keeping an eye out for suspicious activity. Police also encourage neighbors to watch out for each others property.
Tamara Ross lives in the Lake Forest Estates and said her neighbor doesn't order online anymore because she's had such bad luck during the holidays.
"She just doesn't really order," explained Ross, "She said its problem, because people take her order or it never gets to her house. She just doesn't want to deal with it, basically."
At an apartment complex off of Waldron Road, packages aren't allowed to be left at the front door. Instead, a note on the door lets residents know their delivery is being kept safe at the office.
"Nobody wants to spend a lot of money on something and never receive it," said Ross.
The U.S. Postal Service encourages residents to talk to their mail carrier and ask them to put a package off to the side or behind a chair on the porch, for example.
If you think you've had a package stolen, you should immediately call police.
