Junk Mail Or Not

I received a pretty nondescript piece of mail the other day.

I should say, it was in our mail box addressed to resident but the house number was to a nonexistent house.   It stayed on the counter a couple of days.  For some reason I decided to go ahead and open it before I threw it away. 

It was a government food survey that I had no intension of filling out, wanting to know our income and food insecurities.  

But there was a surprise.  At least I got $5 for opening some junk mail.  I hear that $5 can go pretty far at Dollar General.
