I consider myself a polite and friendly neighborhood eBayer. I was watching a bag for a while (seller kept relisting it at lower and lower prices) and I sent them a very deferential message asking if they would consider a certain price. They wrote back immediately and said NO along with a few other rude comments. Is it considered impolite to ask in a friendly way if they would accept a lower offer?? I felt wounded after this exchange and just wanted to know if I am not following proper eBay etiquette. Thanks girls
