If you still have gifts to buy for the holiday season, you're in luck.

Monday, Dec. 17, is "Free Shipping Day," making it one of the few times in life when it actually pays off to procrastinate.

More than 1,400 online retailers have signed up to participate, according to FreeShippingDay.com. Yep, there is an entire website dedicated to the day.

Along with the free shipping, retailers are guaranteeing your packages will arrive by Christmas Eve.
