First, let me say that I am not affiliated with that site in any way.
I visited the site last night and I must tell you that everything about it points to the conclusion that it is a phishing site. The whole purpose of the scam is for them to get a hold of your credit card details. First they tell you that you can make up to $3500/m then on the next page the number jumps down to $500-$1000?! And seriously, have you ever seen a merchant who asks you for your credit card details just so he can charge you 1$ of S&H?!
If you did happen to give them your credit card details, then I would suggest you pay close attention to your future account statement and make sure there is no unauthorized activity (especially online purchases), or just to be on the safe side, change your credit card details altogether.
I wish you a very good day, and good luck against those phisher!
