No one is forcing us to buy an overpriced item ! Market demand drives prices up or down ! While 1/2 the original cost is a fair asking price for common audio equipment , some hand built and limited edition electronics are worth more because they are rare and offer something really special .
Making reasonable offers for products listed with a reasonable explanation for the offer is always welcome by most sellers .
Some sellers are listing high prices to check the market , some are just fishing for fools .
Ultimately it is up to the buyer to do ones homework to determine what is a fair price .
