A few years ago I was a member of Superpoints. I cashed out for paypal rewards quite often, and then they closed the website. I found out last week that it is back!!!
They have changed things up a bit, but there are still many (free) options to earn Superpoints - and you can cash out for different rewards (no more paypal unfortunately).
If you are someone that likes to earn points for things, then you will want to check it out. You can use my referral link to sign up (it's an invite only site)
