Crowdtap is my new favorite site! Just by simply answering product polls and participating in discussions, you can earn cash for the charity of your choice (Make your choice from Crowdtap's list.). You may also get the opportunity to sample products and throw sponsored brand parties.
Crowdtap is free and you can sign up quickly by signing up using your Facebook login. I have linked you through my personal invite code. When you use it, you'll get your first $1 on sign up! Once you sign up, you can refer up to 5 of your friends and receive $1 each for the first 5 friends. Then earn 100 points for each referral after that. The more points you collect, the more opportunities you'll have.
Simply by answering brand specific questions I was invited to join an Old Navy Sample Share "Twirl Into Spring With Old Navy Dress Sampling". I will receive a coupon for a free dress for me and 3 coupons to share/give to friends! Sign up now and let me know what you get invited to try!
