Superpoints is back I used to use this site a few years ago and I found it to be really easy to earn gift cards in. Like most other sites you can earn points from doing offers although what I really like is the SuperLucky button. The superlucky button just requires you to click a button. When you first sign up you get 10 clicks a day and each click is a chance to win anywhere from 1-1000 points. Once you level up you do get more daily clicks and you level up just by using the site. You also get super lucky mail sent to your email and opening it gives you a chance of winning points. They also have a really good referral system in which you get 2500 for each sign up and you will earn whatever amount of Superpoints they earn.
Right now Superpoints is an invite only site so if you want to join. Sign Up Here
