Superpoints is a fun way to earn points for gift cards or money sent to your paypal.
You can earn points by:
--pushing the superlucky button (30 times/day for basic member, 50/day for gold, 100/day for platinum)
--opening emails with points
Im almost to 1000 points with only about a week of being able to use the superlucky button.
It's so easy to upgrade. All you need to do is complete your profile, and have 2 people signed up under you to be gold, then when you have just 5 people signed up under you, you become platinum and can earn even more.
