The reason we tell our customers to clear their cookies and cache is because of multiple open tabs in the browser.
When people are bonus shopping they are comparing bonuses side by side and therefore, we tell them to clear cookies and THEN click our order button to eliminate the possibility of someone else getting credit for the sale.
Often times people think they can just buy and then select which bonus they get later once they're inside. The average person knows very little about affiliate marketing and even less about cookies.
