http://www.synergycash.com - Pays $5.00 bonus just to sign up. Lots of free offers (no credit card required.) Easy money LOL. I got $73 from them last month through Paypal.
http://inboxdollars.com - Got $33 from them a few months ago BUT it took 2 months to get to me after requesting. I still got it though... no huge complaints.
http://treasuretrooper.com - They're pretty good, got $12.50 in my account still. Only thing is that some offers stay pending for a few days.
