TOPIC: A Little Halloween Marketing

My oldest daughter just came home with her candy. We always have our kids dump their bags for inspection, and I noticed a business card taped to a chocolate bar. The card was from a home improvement guy in the neighborhood.
What do you guys think of this? When I first saw it I had a knee-jerk reaction of it being low class. After I thought about it for a while, it really isn't a bad idea for getting your name out there.
Have you ever seen this before? What do you think?

I think I'd agree with both takes, but in the end, "no press is bad press", right?    Seems like a pretty captive audience, I might think about stuffing a few cards if we get any ghouls!
