A few years back, I spotted one for sale at the Kittery Trading Post in Maine. "Well used", as they say. I checked it out but passed on it.
Six months later, they had another one for sale. I said to the guy behind the counter "Gee, I saw another one here six months ago."
He said "Naw, this is the same one. We sell it and six months later, take it back in trade. We've been doing this for years - same gun. Why don't you buy it and in six months we'll give you a really good trade-in on it."
We were both laughing by then - I still passed on it although... would have been neat to own it for a while. Like, maybe, six months?
