well that is sort of what I was asking about, if you use the link to go to amazon, the cookies recognise who you are and take you to your amazon account.
Maybe I have misunderstood how Able-2-Know gets credit from the click, is it just advertising or is it linked to items bought?
I'm guessing now that its just advertising so this thread is a bit redundant. looks like I misunderstood the initial post about Amazon
