Ebay can be soooo frustrating. I tried to resolve the problem with help on chat line which took so long I had to give up.

I tried to list  bone china trio plus extra cup and saucer. The trio is new, but, I found a small chip on the underside of the saucer of the extra. Therefore I decided I should list the trio as new and the extra cup and saucer as used.  In the condition section I chose NEW-OTHER (see details) . 

I thought that would be appropriate. But, It was rejected. A Red sign saying there was something wrong with condition and description. So, I tried again by saying NEW for the trio, then explaining the chip in the description extra saucer as used. NO GOOD. Apparently the word "used" in description affects the "new" in condition. So, what is NEW-OTHER (see details)?

We have to work hard for the meagre amount that's left after EBay takes out their fees including post cost.
