I don' want to spend money to earn money.

If your don't want to invest money to earn money than you were once like me. They don't take your money your buying something but your buying something that helps you make money so lets say you buy 10 referrals on neobux for around $1.10 and 8 of them click 80 times in a month you get
$3.20 that's double the money you used to buy the referrals! So just try it. It would be $6.40 for a golden member.
