I just requested my first payment on Opinion Outpost. To my surprise I got the Amazon gift card code right away. No waiting days or weeks.
Opinion Outpost is a survey only site. They send you an e-mail when there is a survey available for you to take.
I joined on April 18, 2011 and have earned $13.90. I have completed 7 surveys.
You can choose your rewards in either a Visa gift card, Amazon Gift card or a check.
Referrals are done through e-mail address. Send me a message and I can get you referred.
