Interesting Low Cost Marketing Idea

In my mail this morning, I found this interesting marketing mail out from a national surveying company. They actually included a new crisp dollar bill and a survey form. It’s a pretty effective way to get people to respond to direct mail out marketing. The survey would normally have been thrown in the trash immediately, but since they sent me a dollar, I decided to fill out the survey. It was almost like they struck my moral obligations by including the money. How could I not fill out the survey if I accepted the money?
