I have looked in to it, and I don't really understand what commision junction pays you for... can someone else help? Someone with experience please go in to detail?
you promote products for companies. you either get a fixed amount or a % each time you drive a sale or lead to one of their merchants.
if you look at ebay.com , you see that they also do that with CJ. they promote theire products with them . very hard to use in the beginning, but you will get used to it Exp.
