Sales on Sponsor Promo Days. Why is it...
 

I never have been one to start promoting a sponsor just cause they are running some "double payouts on Leap Year Tuesdays" bs promo but I have a couple of sponsors who will run such promos once in a while. When I look back on my stats why is it for nearly every sponsor that does this my ratios/sales for those specific days are 4-8 times worse than the days before and the days after?

Im not talking about the ones that run promos for like the whole month, or a specific pay period (those I dont see much of a difference in my stats)....Im talking about the ones that run promos on only one day a week for a month or something.

Or is the answer obvious?
