You can only post 1 thread in a category in a given day. You must put multiple listings in one thread. Then, you must wait two weeks before relisting any of them which haven't sold.
Alternatively, you can list an item by itself on any given day, but then you can't list any others in that area of the Exchange until the next day.
However, if you have fixed blades, autos, folding, custom, you can post one thread in each separate area of the Exchange on any given day. (But no repeats for two weeks...and no duplicate threads for the same item in multiple areas.)
You can't fix your ads now. They have been merged since they were all posted within minutes of one another. So you'll have to field them in the same thread.
