You are correct, they are everywhere. Maybe too much. I know I have grown weary of them. My wife watches their show sometimes, but I can no longer handle their phony sitcom.
I was paying for my gas at the Quick Trip the other day when I glanced down and saw Duck Dynasty lottery tickets. I was at the liquor store and saw a display of Duck Commander wine. You go to Walmart and half of everything is Duck Dynasty. I can understand them wanting to cash in on their 15 minutes of fame but my God! It's way past the point of over-kill.
