With one of my merchants I have the following problem: since about two weeks I do not sell anything for them although my traffic increases steadyly. When I did a search a lot of coupon sites appear with autocookies, but that is not all: if I click through from my website to that merchant his website is loaded properly but after a short time it is reloaded and session cookies are set. My PID keeps showing up in the status bar. My question is: If the site is reloaded and a sale occures who is credited for it?
