Let me be honest. After two years of association with payloadz.com, I have not made any sale thus far.
Though, Clickbank and ejunkie are preferred by majority of the affiliate marketers, I still firmly believe that Pay Loadz too can be considered as a useful affiliate network because the the range of downloadable products is vast in it.
Even I too have listed my own product in Payloadz.
