Been doing surveys for about half a year already, personally I'd say it really pays off. Honestly being a survey taker isn't my primary job, it's really just an extra for me. Having some dollars to do partial grocery or just buy anything and some reward items from survey points isn't bad at all. You can do surveys leisurely with your own time. Nothing really complicated. Just keep answering the survey invitations and that's it. Good for you if you qualify for that certain survey and if not, just keep doing it... no other way.
Will be posting soon some more recent checks I earned... I think it's the best way to let you all know that you can really get something from the survey sites I listed on my previous posts.
