Yesterday Living Social ran a promotion with McDonald's: $13 for 5 Big Macs and 5 large fries. With 15 hours to go, they have already sold ~260,000 deals... which equates to 1.2 million Big Macs. ~35,000 people shared the deal via Facebook (~13%). I remind you: the deal *still* has 15 hours remaining. What's this all mean? Of Big Macs alone, Living Social sold: 763 million calories 44 million grams of fat 60 million grams of carbs and 31 million grams of protein
When you add in the fries, the total dent is: 1.39 billion calories and 76 million grams of fat
Enjoy!
