Valued Opinions – Decent site with reasonable surveys ($2 for a 20 min survey). Everyone is annoyed by this site because they tacked on a $2 few to the Amazon $20 gift card and $5 to the $20 Visa gift card so it costs $22 to get the $20 Amazon and $25 to get the $20 Visa. They claim its because of extra fees they incur. I dunno. Also, it can take weeks to get credited for a survey which is frustrating.
We've tested hundreds of sites where you can take paid surveys for money and we've found that Swagbucks by far is our #1 pick. They've been around for years and have a solid track record of paying their users. Plus, we also like that they offer opportunities to get paid for doing things other than surveys, like signing up for offers or shopping in their portal.
