Hi there,
I had a buyer wanting to buy a hand bag BIN so I ended the listing, and just changed the format to BIN and she could not finds the bag again as it was not an auction format and did not show up in the search results. I had the exact same listing and only changed one thing. Unless you are an anchor store or do an auction format your listing is invisible. I had to help her find the listing and tell her what to type in and she had it saved to her watch list.
