I have also experienced and don't be confused ebay's processing system
will sometimes be overloaded, usually they will send requests to provide
necessary information to verify you are an ebay user for business or
purchase purposes. It will take about...
go to your account in the left corner on ebay scroll down to "sell" and
select "time way" you will start to stop trading from the time you
choose and end time at the time you want
all the information needed is in the "sale" section and that's the
essentials, you have to do market research the item you want to sell and
much more!!
