Let's think intelligently here. A low offer does not necessarily mean disrespect or hustle. Some people are trying to get bargains because they can't afford the true cost and some people are also trying to move items quickly for whatever reason (relocating to another country). A lower offer can also serve as a bargaining tool. I'm not offended by low offers and don't mean it to anyone. It is just a point of negotiation. If you don't like an offer just let it hang or reject it.
