I just tryed a survey (or something....) for free zylon coins but i checked the list and still none are free u still need to pay 2euro's (around 4dollar) etc.... So why not make it TOTALLY free ? Would be great for other people !
You have to keep looking.
We use the TrialPay survey service. All the surveys are chosen by them, not by us. If you want completely free surveys, you'll have to ask them.
