ICS is Instant Cash Sweepstakes. I've been a member for quite a few months, and I really like it. You can answer a few short survey's every three hours, and have a chance to win some cash, and/or tickets and coins, that are entered into their daily $50 cash drawing.
Refer your friends, family, neighbors, co-workers, or whomever. and when they win, you win!
You must have a Paypal account, so they can deposit your winnings when you cash out.
