I've been a member of Google Opinion Rewards for quite some time and really love it. It's pretty simple, Google rewards you for your opinions. Rewards are in the form of Google play credit that you can use in the Google play store.
HOW DOES IT WORK?
The way it works, Google either sends you random surveys or if you have your location turned on on your phone, Google knows where you're at or where you've been and send you surveys based on your location. Either way, you get a 1 to 7 question survey that you answer and get rewarded with credits.
REWARDS
You don't know the value of the survey until you're done. I've gotten anywhere between a dime and over a dollar. The average is like $0.25. But the rewards add up quickly. Rewards can be spent in the Google play store for games, music, books, etc.
If you haven't signed up, feel free to use the link below. It's really easy to use and easy to earn rewards.
