You won't get rich doing these things but it's legitimate and you'll get paid in the end. For example, you get a penny for each email you click. You get a penny for a video stream. You can earn dollars for fulfilling offers but those aren't nearly as quick as reading an email. They are upfront in what you get paid so you can decide if it's worth it.
The concept of data mining and profiting off that data mining isn't anything new. And while some companies engage in some rather disreputable practices to do this, Global Test Market seems to be doing just fine with the whole “consent to disclose” thing. More importantly, in some cases this may help you as some companies will offer to do more specialized product testing once they've identified you as their target demographic.
Cashback shopping: Who doesn’t love getting cash back? It's a great incentive for shopping because it feels like you're being paid to do so. It's usually best to use the offers only when you were already intending to buy the product. If you love saving money at discount stores or at places that offer cash back, there are a lot of survey sites out there that will open a lot more offers to you. Survey sites can offer cash back because they're paid a portion of the profit for referring you.
In addition to filling out online surveys for money, you can get rewarded for other actions, too.

Valued Opinions – Decent site with reasonable surveys ($2 for a 20 min survey). Everyone is annoyed by this site because they tacked on a $2 few to the Amazon $20 gift card and $5 to the $20 Visa gift card so it costs $22 to get the $20 Amazon and $25 to get the $20 Visa. They claim its because of extra fees they incur. I dunno. Also, it can take weeks to get credited for a survey which is frustrating.
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!
