I have 3 IDs.
I switch my listings around. The higher end stuff goes to my older ID first, after 3 no sales I move it to this ID.
Mostly because this ID gets invited to all the listing sales while my older ID only has the 50 free a month.
Sales are really slow seeing that even the top eBay.Ca sellers don't get best match search results on dot com. One has to avoid listing fees in order to find a buyer...eventually.
The third ID is for my design company. I don't want to mix up old magazines with expensive designer items.
