A marshmallow pie is so popular in North Korea that people are buying it for up to a day's pay on the black market.

In North Korea, workers make an average of $100 to $200 per month. And the Choco Pie is trading for about $10, when in South Korea you can buy the same product legally for less than $1.

The sweet treat is very similar to Moon Pies that can be bought around the U.S. 

Would you pay up to 10 percent of your monthly income for a piece of junk food?
