ADT Security System

I love this coupon we got in the mail from ADT for a "FREE 16-PIECE Home Security System":

If you look at the photo, you will quickly observe:

• The first 7 "pieces" of the 16-PIECE system (44%) are a yard sign and 6 stickers
• The "FREE" system costs only a $99 installation charge, plus "purchase of monthly alarm services"

That deal really sets off my alarms.
