I just got my 13th check from ClixSense! If you haven't joined, you should check it out - the upgrade is worth it too!! I've made well over $140 with this site! You also get $.10 for every referral regardless of whether or not they upgrade! And Premium members will now get paid FIVE LEVELS deep for referrals who upgrade their accounts to Premuim accounts! You heard it right - Five Levels! With the old program you only received $5 for each upgrade you referred. If you referred three, your maximum earnings for those referrals was $15. With our new and improved affiliate program, your max earnings for those three referrals is up to $366.50!!!!!!!!!!

I will think about it.

That's very good payment! congrants!

must i live in the U.S to make money from this program? I'm really interested in it

You do not have to live in US to join - they except international members. See the following post for my link to sign up:
