In a Nutshell
Free Shipping Day makes procrastination possible.
More than 1,000 merchants are expected to offer free shipping on all orders with delivery by Christmas Eve in the contiguous United States.
All you have to do is spend a minimum amount and the service is included at no additional cost. They even ship internationally, however those orders come with some extra charges.
Since shipping is covered with most orders, you're free to use an UnderGear coupon code to get the biggest discount possible.
