I have seen this around blogland for a few weeks and being the slow to jump in person that I am, it has taken me this long to claim my 25$. Its easy though, you just open an account with them (they are like PayPal) and they will start you out with 25$. FREE MONEY....that happens almost never!
If you refer other you can receive 10$. I heard it through the grape vine that Crystal Pain from Biblical Womanhood, actually made $500 in referrals. Not bad!
So if you are interested head on over there and open up your account and get that 25$, you have until May 15th before the offer ends though....so hurry up!
