I haven't sold on ebay in years.
When I did, I made sure to end auctions on a Sunday evening, usually at 8 pm or so east coast time.
I don't understand why sellers would end an auction during the work week, before lunch time.
But I am clearly old school on this topic.
It seems so much easier to have the buyer show up in person and give me the cash.
However, that's not the way the system works, I am well aware.
It's about maximizing profits and it takes a well trained, seasoned seller to play that game well.
