More broadly speaking, much has changed for the retail industry since 2007.
First, improved technology has now allowed for consumers to essentially shop where they want, when they want on their mobile devices and that's making specific days for shopping, like Black Friday less of the big blockbuster day it had been.
This year, we also see evidence of the flattening out of sales with more retailers extending promotions in response to the changing consumer trends.
The National Retail Federation estimates that spending during the Thanksgiving weekend fell 2.9% to $57.4 billion as consumers spent, on average, 4% less this year compared to last year.
A host of big department and discount stores opened their doors on Thanksgiving and extended deals not only through Cyber Monday, but even throughout the week after. Retailers will be pulling out the Hail Mary passes to get shoppers in the door -- or to the Web site or mobile device app -- all month long.
The question remains though, are shoppers already shopped out from the ongoing holiday promotions that started even before Thanksgiving? Could it be that this year's Green Monday is too close to Cyber Monday, given there are typically two weeks between the days to give consumers a reprieve before fulfilling the rest of their holiday shopping needs?
BeFrugal.com's Lal says to expect to see more shoppers looking for deals and using online coupons when they make purchases on Green Monday.
Even though Wal-Mart (WMT) said Walmart.com had its best dales day ever on Cyber Monday this year, the world's largest retailer is using Green Monday as another wholly separate promotional day.
Wal-Mart will be offering more than 300 online specials for Green Monday, with 10 popular deals returning from Black Friday weekend, which includes five of Walmart.com's top sellers from last weekend.
The five top-sellers being featured again for Green Monday include:
- LEGO Fun with Bricks Building Set, 600 pieces for $15 (a $14 savings)
- Canon Black PowerShot SX160 IS 16MP 16x Optical Zoom Digital Camera for $79 (a $90 savings)
- HP 7" Tablet Intel Atom Processor with 8GB Memory featuring Android 4.1 (Jelly Bean) for $89 (a $40 savings)
- SCEPTRE X405BV-FHDR 40" LED Class 1080P HDTV with ultra slim metal brush bezel, 60Hz for $249 (a $150 savings)
- Zoomer Robot Dog with Bonus Hoodie for $79 (a $20 savings)
Wal-Mart is also inviting customers via email, Facebook and mobile to an early shopping event on Sunday, Dec. 8, to be the first to shop 20 of the best Green Monday items before they are widely available.
"The second Monday in December, known as Green Monday, was Walmart.com's highest traffic day in December for two years running, and has always been one of the highest trafficked days of the year," said Joel Anderson, the head of Walmart.com U.S. "With just over two weeks until Christmas, customers who missed out on the great deals last week still have a chance to get the best prices on the hottest gifts, still in stock, one more time."
And once you're done shopping on with Green Monday, don't forget to shop on "Free Shipping Day," set for Dec. 18.
