Pinecone asks for your address because your first payout is sent via check to your address. After a few surveys they offer you a paypal option. As far as sending products to test, these are related to the survey you take. I have been with them for a year and they have only sent a few things for me to try out. In the survey, they ask if you would mine trying the product and you can decline. Pinecone is a great company to do surveys with. I highly recommened them!
