Affiliate Marketing Secrets

Hello All
I am new to internet marketing, i did The 30 Day Challenge by Ed Dale twice. i have two blogs about chocolate and would like to start selling chocolate by famous manufacturers.
Does anyone know the best way to go about this. Should i write to ask for distributors and dropshipping and if there are reliable ones to do business with it.
I have seen lots of sites in this niche.
Many thanks in advance to all
Dori
