I agree with those who are saying keep the surveys. I know they can be a source of frustration. I can spend hours and not get anything. But I decide how much time I spend and it is my own fault if I spend too much time. I do feel they are a good source of earnings for me. I do try to shop through SR when I do online shopping.
Please keep the surveys. I try not to complain when I do not get credit, because as many have said before, you win some and you lose some. I enjoy this site and am very appreciative for all that I have earned.
Thanks so much.
