PineCone Research remains one of the better paying and reliable survey companies, with a payout of $3 for each 15-20 minute survey. The hardest part is getting accepted, as they only accept applications intermittently.
Here is an updated application link at Pinecone. (It probably won’t last long.) Looks open to all ages and sexes. Only one person per household can sign up.
I’ve already shared my thoughts on Pinecone and paid surveys in general here. I call them Bored Money – not terribly efficient but you sometimes get to try some neat things.
The three survey sites that I have been most active with besides Pinecone are NFO MySurvey, e-Rewards, and SurveySavvy. I like it them because they consistently offer me paid survey opportunities, they pay upon request reliably (important!), and they don’t seem to mind if I don’t do every single survey offered.
