It's been, what, a week, since we had a holiday season day with a shopping title of it's own. So, phew. Here's another. It's Green Monday!! No, this is not at all tied to Emerald being the Pantone Color of 2013. The term was coined by eBay to signify the biggest day of the holiday season for online shopping. And indeed, we are two weeks out from Christmas Eve, which is very well weighing on you today as you hit the office, or find yourself trapped at home behind an enormous pile of snow. So just know that if you shop online today, you are likely to find a lot of deals—this website is a good starting point, but visit any of your favorite sites for the latest round of discounts. This, however, is not the last day to score free shipping. That perk has a holiday of its own: Free Shipping Day on Dec. 17.
