I have done a couple of surveys most of them for free and I am entered to win something nice which I never do. I find that they are long and tedious and not something that would be doing for free on a regular basis.
I also like doing surveys. It does provide you with some extra cash. There is one website that I have used and which works well for me. It's called 123cashsurveys.com. I was quite skeptical in the beginning because I thought it would be a scam or something. But actually it really works.
I do loads every day but then, I'm retired so I have lots of free time. They mainly pay vouchers so I usually take Amazon vouchers as Amazon sell just about everything and I bank the vouchers in my account then buy household items as I need tham.
I have yet to find one that will pay anything. I've tried and tried but after all of my effort they may allow maybe 50 cents for the survey. It's really discouraging after all of the effort you spend.
