I have been a member of Pinecone Research for about four years, and it is one of those survey sites that are still worth participating in. While they do not offer many surveys, I usually receive $3 for a survey or product testing opportunity, and I love their product tests.
Pinecone Research is now accepting new applications, and if you are looking to add a little extra to your paypal account while influencing major brands and getting products to test I can highly recommend signing up for Pinecone Research.
IMPORTANT: ONLY ONE PERSON PER HOUSEHOLD MAY REGISTER
