Once you wrap all of your holiday presents and take them to be shipped, the work is just getting started for the folks at UPS. Rachael's buddy Justin Willman tags along with the men in brown to see how they manage the heavy load and he also picks up tips to get you ready for the holiday season.

Don't ship perfume. They may be popular gifts, but the government prohibits the shipment of cologne and perfume as they contain alcohol and are flammable.

Inspect your shipping boxes. It's best to use new boxes, but if you want to reuse them make sure they are in good condition and the structure is strong before they are used to ship another gift.

Batteries not included. For electronics and toys keep the batteries separate as they can leak and destroy the gift. And, if it accidentally turns on and the box makes noise the package will be destroyed out of security concerns.

Stick to clear packing tape. The clear tape will hold up better during the trip than masking or duct tape.
