A credit card is required for this. You cant use the same credit card number, but if you have online banking, most online banking things allow you to create a online shopping number (so does paypal), and you can continue generating new ones.
It costs $15 to sign up, and i will pay you $16 per signup. However, lower bids, and higher amount of registrations will have priority. So if you are willing to do it for less than $16 per signup, let me know in your bid. Also, let me know how many you can do for me.
I believe they only allow US signups via credit card, but i think they accept paypal if you use the contact us link.
payment will be made to you when the commission is triggered to us. This can take anywhere from 5 days to 35 days depending on the exact period of signup.
