Have you guys ever heard of Winzy search? It's kinda a freebie. You use their search engine as you would normally use Google or whatever but you can win prizes. I downloaded a search box so that I would remember to use them. For each search you get points even if you don't win a prize. Those points go towards entries into the monthly sweepstakes. Also if your friends join under you, whatever you win- they win and vice versa. I thought it was kinda cool.

Here's the my link to it : http://www.winzy.com/tracey22
