OK. This is from a buyer's point of view.
I've often perused the sales ads on this website. I've even talked to some over the phone with some of the people who were selling products I had interests in. After an elongated lapse of time of hearing them go gaga over the item they are selling, I would eventually ask, just why in the world are you letting this baby go? Three out of the last five answers they say they have to unload gear due to the pending new member of the family. This is all within 2 days. Can this be for real? So, maybe I can postulate there is a direct linear relationship between birth rate and the number of high end gear for sale.
What's really interesting to me is when I read, "I bought three of these, and I really only needed two. Therefore, instead of returning them, I will sell them on the used market for half price."
What's really sad is when the poor old chap tells me he's been out of work for years and need to provide for the family. Thus, he's got to sell. Really, this happened with this gentleman when I was acquiring an amp that I eventually bought. I wished him good luck on finding a job, and he sent me a partially damaged amp.
I guess this proves your point in a round about way--there is no point in asking. However, it is a pretty good conversation starter.
