WASHINGTON, DC (WUSA) -- Millions of holiday shoppers have spent billions.
But people who did miss out on Thanksgiving doorbusters, Black Friday deals and Cyber Monday specials still have plenty of big shopping days left.
It starts with major retailers like Amazon, Target, Walmart and Best Buy who stretch Cyber Monday deals through a cyber week.
For years e-tailers noticed a spike in sales on the second Monday in December when consumers realize they're getting tight on shipping time.
In 2007, eBay named that day Green Monday. And, this year it falls on Monday, December 10th, along with special deals from many retailers.
Monday, December 17th marks the fifth annual Free Shipping Day.
It's when hundreds of retailers will offer free shipping and other special offers to online shoppers.
And delivery of those holiday packages to the lower 48 states are guaranteed by Christmas Eve.
By December 22nd it's usually too late for online purchases. So, the last Saturday before Christmas has come to be known as Super Saturday.
A day when shoppers rush into stores to make last minute buys.
It's also when retailers will make deep discounts on merchandise to move it off of store shelves.
