I always end my auctions between 9 p.m. and midnight eastern time. Best time to end an auction is Sunday, but any day between 9-12 is good. Maybe not a Friday night.
I usually do a standard 7 day auction. If it is a hot item that is going to cool off fast like the spidey stuff a 5 day auction might work well.
Am I going to learn karate?
The Dane Cook of martial arts? No.
