Update: As of 12/31/2011 SayNation.com will be closing it’s doors.
SayNation Survey Panel is a very good paid survey site. They have many surveys, and their surveys are short, easy and interesting. You earn points for completing every survey, and points are redeemable for cash (via Paypal), amazon gift cerfiticates and prizes. I have redeembed amazon gift certificates a coule of times and I received my rewards (they emails me the amazon gift codes) in 3 days.
SayNation is also a fantastic survey sites for teens. They actually have a teens panel for teens 13 years and older.
SayNation survey panel accepts members from United States.
SayNation has a referral program, if you sign up using your friend’s referral code (and you take some surveys), your friends will get 1200 points referral bonus.
SayNation no longer gives points for new member registration even if the new member uses a friend’s referral code to sign up. Only the friend who refers you get referral bonus.
I took several surveys and have 7600 points already, the surveys are really easy and short! I also continue to cash out Amazon Gift certificates, and usually receive the reward within a month.
Overall, SayNation is a great survey site, and I recommend it!
