If you thought Prime Day was the first ecommerce shopping holiday, you’ve got it all wrong. It’s Green Monday.

Yep. Green Monday. eBay first coined the name around 2007 to describe their busiest shopping day. Now, this increasingly popular online shopping day is the second Monday in December, fitting in after the cyber Monday rush but with enough time to ensure packages arrive before Christmas.

According to Statista.com, in 2014 online consumer spending on Green Monday was just over $1.6 Billion.
