Get Free Stuff By Filling Out Questionnaires Has Anyone Recieved Any Of The Free Stuff By Filling Out The Survey Questionnaires?

Has anyone recieved any of the free stuff by filling out the survey questionnaires? - get free stuff by filling out questionnaires

You know the "Free Gift Card, which offers" or "free", what you say when you offer the complete questionnaire. I tried to time it on and it took me a few hours to get through a large number of studies before I'm tired and quiet. So, all I received a number of complaints against spam e-mails from a group of different companies. Has anyone one of those things and actually get the free offer?
