I'm really random with listing, I do some in the AM, afternoon, and evening, sometimes on weekends. Evenings appear to be better, usually my sales come Mid morning or late at night after I'm in bed. A lot of sales come from posting on fb for me. I don't know if there is really a "best" time list. This time of year is a bit slow for me, but then again I am not listing new items that often or renewing that often, truthfully I don't want to be that busy right now. I would suggest renewing the items that have an older listing date on them, I believe I saw one from March 6th. Get your items back to the front for viewing, this will help you a lot! On days I renew, not list new items, I get an average of 2 to 3 sales in that one day.
