I will give an example... A person click my aff link and entera amazon and buy something, after he checked out and finish buing he decided to buy another product, the person buy it, amazon does not pay commision for the second sale, i have checked it twice and the second, third..ñ sale is just ignored by amazon, they don't count it as a valid sale. Why? I have brought a client to their website and they count only the first sale... :-(
That's weird. I have had people buy multiple items and they were items I didn't even have listed on my site. It should count them though.
See Section #7 of the Operating Agreement Point (b) says, you only get paid when customer checks out "during single session".
