I've been a member of Pinecone Research for over a year. It's website where you take surveys and are occasionally sent product trials.
You earn $3 for each survey and product trial you successfully complete. I've already earned over $100 from the website.
Pinecone is looking for new members, more specifically households of Hispanic/Latino descent.
It's rare that they open membership so join now: http://www.pineconeresearch.
