I've been reviewing on Capterra for a few months now. For each review, you get a $10 Amazon e-giftcard. You have the option to review up to 10 times each month, giving you $100/month in Amazon credit. Then, the next month you can do it all over again - earning up to $100 in Amazon credit. It typically takes 2-3 weeks for Capterra to send you the credit, which is in the form of a secured redemption link. Awesome opportunity for some extra cash on the side.
