When you log on with your acct and you go to charge acct. You will see there it says earn free NX. There are some ******s there you can do to get free NX. I did a couple and too pussy to complete the rest cuz they look so dangerous. But I only completed the health newsletter(s urv ey) one where you get 192 NX. God I really can't go any further with these type of things.
