i plan to set up first cashback website where I will offer my members money back if they buy something from merchant listed on my website. Problem is i dont have a lot of experience. About what i gotta be carefull? What is the best way to find merchants and how to link my website with the merchants website so I could see when the payment is made and sent to my account? is it simple? How much does it cost to set up an afilliate program?
