Become a Submission Pro! referral member and they will pay you $50 for every person that you refer who purchases a copy of Submission Spider for Windows. There is no minimum like most referral programs. If you refer only one person they still pay you $50. Basically, they give you a URL with your own referral code on it. Then anyone who purchases a copy of the Submission Spider from your referral URL gets recorded. Pays monthly. Discovered by Dmitry Kirillov..
