Now I am annoyed and I am venting.
Just took a 25 minute survey from Greenfield for pain relievers.
I had to evalate different ads and tell them if I remember them and which brands they were for. I answered about 50 questions. Then AFTER all the classification questions at the very end, instead of the thank you from Greenfield page, I got "sorry but you don't qualify". I wasted my whole lunch hour on this.

I am cashing out now and not going to do surveys for awhile.
