MindMover is looking for new people to join their survey site and earn vouchers! Just make sure to complete the initial questionnaire and verify your email to be able to get your gift card.
To sign up, click 'GET FREEBIE'. Then just complete the registration questionnaire - once done, make sure to verify your email address. Then, once you've verified, log into the account that you've just created and you'll be taken to your own MindMover account. You can find new surveys here - check back whenever you like to see if there's something new.
Once you get enough points, you will be able to withdraw them as a £20 Amazon gift card.
