Free Shipping Day started back in 2008 and it's been growing ever since.
In fact, Free Shipping Day last year featured deals from more than 2,600 merchants and generated more online sales than any other Friday in history, with more than $1 billion dollars spent.
And while most merchants do offer free shipping with guaranteed Christmas Eve delivery, there are other deals as well, including Buy One, Get One Free and percentage-off coupon codes.
The Free Shipping Day site offers a convenient list of the participating retailers, and you can simply click on their names to see what they're offering.
You can also find a list of shipping deadlines by store, so you know just how long you can procrastinate and still get gifts to their recipients in time for the holiday.
