I was speaking more on the terms of the merchants tracking not working properly. In my 2 purchases I saw the clicks but the commission didn't go through. It was not a fraud purchase, was not using a stolen credit card...eveything was legit.
Wouldn't you hate to think a merchant didn't quite set something right and they were getting these sales and didn't have to pay their affiliates any commission. Just makes you wonder when you see your own sale drop through a crack and how many other times this might have happened.
Am I able to post the merchant names here to warn others that it might happen to them and to be cautious?
