Participating retailers include everything from giant department stores to independent Etsy stores. Some require codes to get free shipping, which can be found on the Free Shipping Day website. In order to be listed on the site, merchants must offer free shipping on all orders with no minimum purchase requirement, and those orders must arrive by Christmas Eve.
Free Shipping Day was started nine years ago, and first generated $1 billion in 2011, according to the site.
