Buyers will have many reasons for choosing who to buy from and not necessarily based on cheapest price alone.

When I bought from you for example, I had done a search for the cheapest items.  I then narrowed it down to sellers in or near Sydney because I wanted some of those items fairly quickly.  I could have bought cheaper but chose delivery time instead.

Unless sellers can guarantee that they have completely unique items they have to be prepared to have competition in selling and a listing title should not make any great difference.
