what is the benefit of asking "what is the price?" if 99% pass you the ball back? why not open the conversation with a starting offer? we all know the rules of negotation. for me it is a put off to have people beating around the bush all the time.
with property that is fsbo, (homes, cars, etc,) typically the owner sets the asking price (generally in line with market value of course). however, consider that perhaps the most popular adage on the topic of domain appraisal is: "a domain is worth whatever a buyer is willing to pay for it"
given that, it seems the price of domains have a higher elasticity in their ceiling than they do in their floor. so I think you can see why it is normally not in the owners interest to open. If the owner opens with an asking price then the ceiling is set. there is almost no reason to set the ceiling when supply and demand is so stilted to the owners favor. As the owner I realize there is only one of my supply and since you are in demand for it i want to know how deep your pockets are, therefore in opening the negotiation let us set the floor first and see where you are coming from.
when the first thing i hear is "what is your price?" more often than not it ends up just someone who was beating around the bush, ie. fishing for a bargain. :imho:
