Anyone ever heard of it? I never did until a few minutes ago when I was on Walmart's website and saw a promotion for it. I had to google it to find out the actual date (it's this coming Monday, Dec. 10, btw).
From examiner.com"
"Green Monday is the second Monday in December, usually a big day for retailers as shoppers begin to realize Christmas is less than three weeks away, and time for ordering items for Christmas delivery is running out."
So, do you have any big plans for your shop on Green Monday? I don't, considering I'd never even heard of it until now.
