Few questions: How do you setup an incentivized site? When a person places an order how do you track their sale? So the right person gets credit for the sale also so you know for sure this particular person brought you the sale. Do you wait until you get paid and tell them all incentives are given out at the end of the month? What about do you have to give them a form to fill out their address if the incentive is an item, or ask for their paypal address if it's cash? Or do you make the incentive a contest saying that one person will win the big prize?
