If you haven't already begun eating Halloween candy, it's time you start. Friday is National Chocolate Day, a holiday created by the candy makers at the National Confectioners Association.

Americans eat more than $18 billion in chocolate every year, which evens out to about 9.5 pounds annually. And the United States isn't even the top cocoa consumer: In Switzerland, residents eat about 19.8 pounds of chocolate every year. In Germany, it's 17.4 pounds, and in the United Kingdom people enjoy just over 16 pounds of the treats, according to Forbes.

If you're trying to get your numbers higher, Friday is a good opportunity. Several retailers are offering promotions on chocolate for the holiday. See a few below:
