We try to list everything we buy, as buy it now. Then we will auction a lot every month too. That way everything is shown and I can manage 30 auctions a week. I sell maybe 20-30 bin items a month. Then come the colder holidays we will auction more but at least the item has been listed so there is a chance it will sell. The only problem I have run into is that after something being listed for a year, after it sells is finding it in the room!
