Well I've been using it for years, like 5 years now. The website formerly known as Email Cash. It's a website where you earn points by doing quick surveys, detailed surveys, clicking ads, viewing emails and by shopping with rewards partners...there are also a few games of chance that you can risk your earnings on.
My referral (I will make 200points for every person I refer who makes 400 points) link is HERE
...or you can visit the regular site at www.rewardscentral.com.au
100 points = $1, however you can only cash out (direct debit, or cheque...or donation to charity) at $30 or $100 - And there's a processing fee of 300 points ($3) for $30 cash out or 100 points ($1) for $100 cash out.
One nifty thing about this site is that there is an e-bank which earns interest on any points you have I have enough for a $30 cash out but I have it in the e-bank making better interest than what the leading banks offer, and on a deposit amount they'd never touch!
Generally speaking you can earn a minimum of 2 points every day by opening a 'web click' link, every so often I will be offered a quick survey (answer one question) earning 3 points, a lot of emails have been coming through lately it seems with the offer of 5 or 10 points for every one you open...it literally takes a couple of seconds to do.
If I get a regular, full length survey and I'm in the mood and the subject matter doesn't bore me to death I will fill them out. They are generally worth a few dollars...I've done one in the past that paid $20! Which I then invested in the e-bank at like 8% interest.
What I do is do my little ritual of visiting the site daily and getting the easy money than investing it in the e-bank, by Christmas time I have a nice little bonus :)
Check it out yourself, however, I believe it is restricted to only Australia
Good luck!
