When McDonald'(MCD -0.05%) starts buying ingredients, it tends to buy a lot of them. For example, the  company sells 9 million pounds of fries every day, which means that it needs to purchase hundreds of millions of pounds of potatoes each year.

That huge appetite for food has had Buffalo Wild Wings' (BWLD) investors nervous as Mickey D's adds chicken wings to its menu nationwide. The worry is that McDonald's could buy up so many wings that it pushes prices up and cuts into B-Dubs' profits. But that doesn't appear to be happening.

In the video below, Fool contributor Demitrios Kalogeropoulos says that Buffalo Wild Wings' management isn't concerned about wing prices jumping up on account of the fast-food king and that clears the way for a big improvement in B-Dubs' profit margin in the second half of 2013.
