Also, what percent PPC should I aim for as an end goal? and what are some PPC stats you guys recommend? aggressive, non aggressive? i can’t post images so this is how it is selling price 129.99 buying price (from china) 37.57 shipping 4.5 profit 44.42 per unit (after amazon fees) 34.17% profit margin this is before PPC though so do you guys think this will be okay or will i go red? also what are some ppc stats you guys use that work well? thank you
