Hi,
StudioEleven, your sales might be best on Tuesdays and Wednesdays because perhaps you are most actively updating your site on those days? The majority of my activity occurs in the late morning and early afternoon, which also happens to be the time that I am on the computer. I always list items during that time to get the East Coast buyers who are 3 hours ahead of me, and then I list again to get the West Coast buyers in my own time zone. Since I'm already at the computer, that's also when I edit listings, browse teams and create treasuries.
However, many of my sales are in the mid- to late- afternoon, when people are coming home from work or school, or maybe an hour or so after they have been browsing.
