Check out Pinecone Research: Earn Extra Cash

 Stretching A Buck has a link to Pinecone Research available right now. If you are interested in this survey site I would sign up now. Spots fill up fast and not everyone is accepted. You don't receive many surveys a month from them but they do pay you $3 for each survey.

I signed up over a month ago, received only one survey from them, but 5 days later I received my check in the mail. I would highly recommend this survey site.

Sign up is now over.
