Scams and other free things

Is there are word for something that is free, but really is just a sales pitch in disguise? If there isn't a word, there should be. How about really f***ing annoying? Or maybe, scam? Both of those seem to fit nicely.

I just got a call from a Terminix tele-marketer asking me when I want to schedule my "free" termite inspection. Of course they already tried this trick on me once when I bought my current house almost five years ago. Basically, they inspect for termites and set there standards really low. Meaning if they see termites in the ground within six feet they call you over and tell you horror stories about houses falling apart, etc. Then they tell you about their Centricon system which they developed for the Navy, blah, blah, blah.

Basically, my house is surrounded by trees. Trees are made of wood. Termites eat wood. So you'll find termites in the ground around my house. Finding them in the ground right next to a house is cause for concern.

Of course, I had to figure this out the hard way the last time I got a free inspection, by freaking out, calling the person who did my home loan and getting a free visit from the person who did the original termite inspection.

The people who do these inspections are a separate group from the people who service your house. I'm almost 100% sure they are commissioned sales reps. Bastards.
