P r i z e l i v e .com officially launched in May 2008 and has been paying out thousands of dollars in cash and prizes every month to its members (worldwide friendly). Best of all, ALL PayPal cashouts are processed instantly. The minimum to cashout is only $1 so it is very easily attainable. Prize Live has all sorts of contests (Offer, Referral, Forum, NBA, Most Popular, etc.). New offers are added daily (usually 5-10 new ones at least for USA members). There is also a monthly Jackpot that has been reaching at least $400+ per month, which is split amongst at least five members.
I'd like to let everyone especially know about the weekly Offer Contest that Prize Live has. The top ten members with the highest scores each week win cash prizes and Game Credits. Five random members with at least one completed offer will win as well. Check out the image below to see the prizes for it:
