You know what they say: The early bird gets the worm.
Well, this year, the playbook has changed. Sorry, early bird. It's the late bird that's going to get the worm this year.
Retailers are going to be pulling out all the stops this weekend — the last weekend before Christmas — with everything from jaw-dropping markdowns to round-the-clock openings in a last-ditch attempt to save the season.
Barneys and Saks are among the slew of retailers offering 75-percent off, Dana Telsey, of Telsey Advisory Group, told CNBC.

"You will go in the stores and you will see coupons that are photocopied to say 'Take another 25 percent off,'" Barclays Capital analyst Robert Drbul told Reuters.
