Earn $25 in Amazon by referring your friends to It's Thoughtful (itsthoughtful.com). This referral program runs until 12/15, and all you need to do is refer 15 friends who sign up at the site. Aside from that referral aspect, make sure you enter to win the $500 Amazon card in the Christmas Gift Contest. What you do is submit a gift idea. It is very easy - I did it in less than 2 minutes - and then you're entered. The gift idea with the most votes wins the $500 and if someone you invited wins the contest, then you win a $200 Amazon gift card.
I'd love to refer you to this contest... please click here if you're interested!
