I noticed an interesting thing with a well known affiliate program markethealth.com, former Joebucks.com When I click on a link to any of their shops like http://www.venapro.com/order.php?aid=MyAffiliateId or http://www.acnezine.com/?aid=MyAffiliateId or any other... My affiliate id is substituted with another affiliate id 680256 and it happens on a random basis! In most cases 50% of the time!!! I got curious to check where the problem was, so I tried 3 of my browsers IE6, Mozilla Firefox and Opera. Each time I deleted all the cookies. What I found out is that even more than 50% of the time it showed affiliate id 680256 instead of mine, the randomizer is somewhat more complicated, some day it shows my own affiliate id, the other day it shows affiliate id 680256 and sometimes it randomizes during one day. I wonder if it's only me who has this problem?
