Your opinion is worth points! At the GfK Panel you receive a compensation in points for your participation in surveys. These points can be saved and redeemed for nice gift cards in our gift shop. The number of points you receive depends on the survey you are participating in. If you have saved 2,000 points, you can redeem them for a voucher of €10.
