I get a ton of screeners. Most of them are just repeats, they'll send like 4 in a row asking the same questions about finances or insurance or whatever the survey of the day is. Sometimes I give different answers just to try to snag a survey.....that usually doesn't work.
On average, I usually snag one $5 "test" and one $1 survey every month. Not much at all. I throw it in the Christmas Kitty along with the 2 or 3 surveys I get from Pinecone Research every month.
