There are stores in large buildings, small buildings, private homes, shopping plazas, and every other conceivable venue. Search from among these to find one that meets your needs and fits your style. If you need to listen carefully before making up your mind, discount stores can be very frustrating. If you know exactly what you want, then this can be a great place to save money. Don't expect knowledgeable sales help or after-sale support.
Most people feel that it is fair to negotiate.
Some feel that it is fair to lie in negotiating, as the sales people frequently lie to you also. Others think that lying to get a lower price is an immoral practice. It may even be illegal, an act of fraud. Some people feel that if you negotiate over price, you encourage stores to mark prices artificially high, so that the stores have room to negotiate. Others feel that in negotiating, you are asking the store to accept a lower profit, or asking the sales person to take a lower commission and are directly hurting them.
