One of the top survey sites is Pinecone Research. They actually pay out $3.00 per survey via Paypal or check. They also frequently offer product testing that goes along with them. So, they are a company that I’d recommend.
Right now they are accepting new applicants!! If you are at all interested in applying, I’d do so before they close this down for new applications! It’s great to get paid to tell people what you think!!
