I think part of the problem, if it is actually a problem, for a lot of the guys on this board is that we often know more about the specific gun we are looking for than do the dealers. Sometimes I am looking for a specific configuration and condition level, so I either ask a lot of questions or examine the gun closely, or both. If it doesn't meet my criteria, I pass on it. If it's close to what I want, I'll make an offer, maybe buy or not depending on seller's response. That doesn't make me a tire kicker. I know what I want.
In other cases, there are those targets of opportunity that pop up from time to time and grab my attention. If I'm looking for a 20 ga Parker and stumble across an Elsie Crown Grade, I'm interested. Last time that happened, I bought the Crown after some back and forth. Other times I have walked away without making an offer. That does not make me a tire kicker, either. Retail is retail, and you have to work with the customers.
