After you sign up, you’ll receive surveys on various topics and products via email. Once you complete these surveys and build up a stash of “points,” you can redeem them for cash via PayPal, purchases made through Amazon.com, or gift cards to various retailers. As an alternate suggestion, you can even redeem your rewards as a donation to the Red Cross.
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.
Paid survey site companies invest billions of dollars into marketing research online. They always want to find out more intricate details of a consumer's relationship with their product. Whether it's a new television show or just an existing product line, companies like Disney, Samsung, and Sony go to great lengths to find out their ideal audiences.
