With IP tracking added in, you pickup returns without cookies attached. We figured this was due to people blocking the cookies or deleting them and probably the reason why 7 day-lifetime never really made a noticeable difference in cookies alone.

For the purpose of affiliates and that random guy that might buy months later, set it as long as you can... in the end, it makes affiliates happy and makes no difference either way with the program or sales or profits.
