It was my understanding that after you exhausted your allotment of free insertions that you would be charged an insertion fee BUT that fee would be credited back to you if your item sold.
That doesn't seem to be the case on my May invoice. After my allotment of free insertions, ALL of the others were charged a 30 cent insertion fee. All of these listings sold.
I don't see any credits or reversals of the insertion fees on my invoice.
Not happy!
